## 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.

Problem 6b:

The answer is *x*=2

Check the solution by substituting 2 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:

- Right Side:

Since the left side of the original equation equals the right
side of the original equation when the value 1 is substituted for x,
the solution x = 2 is verified.
