## 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 3:

Add 2 to both sides of the equation:

Divide both sides by -8:

Reduce the answer.

The answer is .

Check the solution by substituting 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:
