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:
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:

Right Sides:
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 = 1 is verified.
