1. Equations With Fractions
Lesson 4-6

2. Remember the Process: Isolate the variable
Perform the inverse operation on the side with the variable.
Perform the same operation on the other side of the equal sign.

3. Example:
y + 3 = 11
- 3
- 3 y = 8

4. Now with fractions: 2 1 1 - b =
x 1 9 3 9 2 2 6 + +
x 3 9 3 3 7 b = 9

5. Now With Mixed Numbers:c + 5 = 11
x 3 11 4 5 15 9 6 18 - 5 - 5 5 4 4
x 2 8 9 9 18 c = 6 7 18

6. Check: Substitute the answer in the original equation.+ 5 = 11 4 5 9 6 6 7 + 5 = 11 4 5 18 9 6 11 6 7 + 5 = 8 5 6 18 18 11 15 = 11 5 18 6
