x / 2 - x = 3 x / 8 - 11
- x / 2 = 3 x / 8 - 11
Add 11 to both sides.
- x / 2 + 11 = 3 x / 8
Add x / 2 to both sides.
11 = 3 x / 8 + x / 2
11 = 3 x / 8 + 4 x / 8
11 = 7 x / 8
Multiply both sides by 8
88 = 7 x
7 x = 88
x = 88 / 7
- x / 2 = 3 x / 8 - 11
Add 11 to both sides.
- x / 2 + 11 = 3 x / 8
Add x / 2 to both sides.
11 = 3 x / 8 + x / 2
11 = 3 x / 8 + 4 x / 8
11 = 7 x / 8
Multiply both sides by 8
88 = 7 x
7 x = 88
x = 88 / 7
