## Step-by-Step Math Problem Solver

Enter an equation along with the variable you wish to solve it for and click the Solve button, **math solve problem**. In this chapter, we will *math solve problem* certain techniques that help solve problems stated in words. These techniques involve rewriting problems in the form of symbols. For example, the stated problem. We call such shorthand versions of stated problems equations, or symbolic sentences.

The terms to the **math solve problem** of an equals sign make up the left-hand member of the equation; those to the right make up the right-hand member. The value of the variable for which the equation is true 4 in this example is called the solution of the equation. We can determine whether or not a given number is a solution of a given equation by substituting the number in place of the variable and determining the truth or falsity of the result, **math solve problem**.

Solution We substitute the value 3 for x in the equation and see if the left-hand member equals *math solve problem* right-hand member. The first-degree equations that we consider in this chapter have at most one solution.

The solutions to many such equations can be determined by inspection. **Math solve problem** Section 3. However, the solutions of most equations are not immediately evident by inspection. Hence, *math solve problem* need some mathematical "tools" for **math solve problem** equations.

In solving any equation, we transform a given equation whose solution may not be obvious to an equivalent equation whose solution is easily noted.

The following property, sometimes called the addition-subtraction propertyis one way that we can generate equivalent equations. If the same quantity is added to or subtracted from both members of an equation, the resulting equation is equivalent to the original equation. The next example shows how we can generate equivalent equations by first simplifying one or both members of an equation.

We want to obtain an equivalent equation in which all terms containing x are in one member and all terms not containing x are in the other. If we first add -1 to or subtract 1 from each member, we get. In the above example, we can check the solution by substituting - 3 for x in the original equation. The symmetric property of equality is also helpful in the solution of equations. This property states. This enables us to interchange the members of an equation whenever we please without having to be concerned with any changes of sign.

There may be several different ways to apply the addition property above. Sometimes one method is better than another, and in some cases, the symmetric property of equality is also helpful, *math solve problem*. In this case, we get. The solution to this equation is *math solve problem.* Also, note that if we divide each member of the equation by 3, we obtain the equations. In general, we have the following property, which is **math solve problem** called the division property.

If both members of an equation are divided by the same nonzero quantity, the resulting equation is equivalent to the original equation. In solving equations, we use the above property to produce equivalent equations in which the variable has a coefficient of 1. In the next example, *math solve problem*, we use the addition-subtraction property and the division property to solve an equation.

The solution to this equation is Also, note that if we multiply each member of the equation by 4, we obtain the equations.

In general, we have the following property, which is sometimes called the **math solve problem** property, **math solve problem**. If both members of an equation are multiplied by the same nonzero quantity, the resulting equation Is equivalent to the original equation. In solving equations, we use the above property to produce equivalent equations that are free of fractions. Example 2 Solve. Example 3 Solve, **math solve problem**. Now we know all the techniques needed to solve most first-degree equations.

There is no specific order in which the properties should be applied. Any one or more *math solve problem* the following steps listed on page may be appropriate. Steps to solve first-degree equations: Combine like terms in each member of an equation.

Using the addition or subtraction property, write the equation with all terms containing the unknown in one member and all terms not containing the unknown in the other. Combine like terms in each member, *math solve problem*.

Use the multiplication property to remove fractions. Use the division property to obtain a coefficient of 1 for the variable. In the next example, we simplify above the fraction bar before applying the properties that we have been studying. Equations that involve variables for the measures of two or more physical quantities are called formulas. We can solve for any one of the variables in a formula if the values of the other variables are known.

We substitute the known values in the formula and solve for the unknown variable by the methods we used in the preceding sections. It is often necessary to solve formulas or equations in which there is more than one variable for one of the variables in terms of the others.

We use the same methods demonstrated in the preceding sections. In the above example, we solved for t by applying the division property to generate an equivalent equation, *math solve problem*.

Sometimes, it is necessary to apply more than one such property. Home About Contact Disclaimer Help. Equations Solve Basic Intermediate Advanced Help Enter an equation along with the variable you wish to solve it for and click the Solve button. Solve Random Solve.
