**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 operation, multiplication and division are completed before addition and subtraction.**

LINEAR EQUATIONS - Solve for *x* in the following equation.

Example 1:

Subtract 3x from both sides of the equation:

Add 6 to both sides of the equation:

Divide both sides by 2:

The answer is *x * = - 1

Check the solution by substituting -1 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.

- Left side:
5(-1) - 6 = - 11 - Right side:
3(-1) - 8 = - 11
