Simplify 1/3 (6x - 15) to 6x - 15/3
6x - 15/3 = 1/2 (10x - 4)
Factor out the common term; 3
3 (2x - 5) / 3 = 1/2 (10x - 4)
Cancel out 3
2x - 5 = 1/2 (10x - 4)
Simplify 1/2 (10x - 4) to 10x - 4/2
2x - 5 = 10x - 4/2
Factor out the common term; 2
2x - 5 = 2 (5x - 2) / 2
Cancel out 2
2x - 5 = 5x - 2
Subtract 2x from both sides
-5 = 5x - 2 - 2x
Simplify 5x - 2 - 2x to 3x - 2
-5 = 3x - 2
Add 2 to both sides
-5 + 2 = 3x
Simplify - 5 + 2 to - 3
-3 = 3x
Divide both sides by 3
- 1 = x
Switch sides
x = - 1
