SOLVING LINEAR EQUATIONS

Recall the following:

• A linear equation is a polynomial of degree 1.

• In order to solve for the unknown variable, you must isolate the variable

• In the order of operations, multiplication and division are completed before addition and subtraction.

LINEAR EQUATION - Solve for x in the following equation.

Example 2:

Add to both sides of the equation:

Divide both sides by

The answer is

Check the solution by substituting or 1.87024209576 in the original equation for x. If the left side of the equation equals the right side of the equation after the substitution, you have found the correct answer.
