## 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 1:

Add 4 to both sides of the equation:

Divide both sides by 2:

The answer is *x * = 7.

Check the solution by substituting 7 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.
