1. Solving Equations
Involving Fractions
Solvin g Equations By Adding Like Terms

2. Example 1:
3/4x - 2 = -14
4(3/4x) -4(2) = 4(-14)
3x - 8 = -56
3x -8 +8 = -56 + 8
3x = -48
3x/3 = -48/3
x = -16

3. Example 2:
(you try this one)
(you try this one)
2/3x + 4 = 14
3(2/3x) + 3(4) = 3(14)
2x + 12 = 42
2x + 12 - 12 = 42 - 12
2x = 30
2x/2 = 30/2
x = 15

4. Example 3:
3/4x - 3 = 1/2
4(3/4x) - 4(3) = 4(1/2)
3x - 12 = 2
3x - 12 + 12 = 2 + 12
3x = 14
3x/3 = 14/3
x = 14/3

5. Example 4:
2x - 5 + 3x = 15
2x + 3x - 5 = 15
5x - 5 = 15
5x - 5 + 5 = 15 + 5
5x = 20
5x/5 = 20/5
x=4

6. Example 5:
(you try this one)
(you try this one)
4x + 7 - 9x = 28
4x - 9x + 7 = 28
-5x + 7 = 28
-5x + 7 - 7 = 28 - 7
-5x = 21
-5x/-5 = 21/-5
x = -21/5
