1. Fractional Equations
Chapter 7
Section 7.4

2. Objective
Students will solve fractional equations

3. Concept
An equation with a variable in the denominator of one or more terms is called a fractional equation. To solve a fractional equation you can multiply both sides of the equation by the LCD. You can also solve a fractional equation as you would solve a proportion when the equation consists of one fraction equal to another.

4. Concept
Remember that the denominator of a fraction can not equal 0. Once you find an answer, put it back into the equation to make sure it does not give you 0 in the denominator. If it does, that number is not a solution to the equation.

5. Example
3 – 1 = 1 x 4 12

6. Example
2 – x = 4 3 – x 9

7. Example
2 - 2 = 1 b2 – b b - 1
