Problem: how to solve 52-x/5 = x/8
i don't know how to solve

52 - x/5 = x/8
-x/5 = x/8 - 52
-x/5 - x/8 = x/8 - 52 - x/8
-x/5 - x/8 = -52
40(-x/5 - x/8) = -52 * 40
-8x - 5x = -2080
-13x = -2080
-13x/-13 = -2080/-13
x = 160

And check it...

52 - x/5 = x/8
52 - 160/5 = 160/8
52 - 32 = 20
20 = 20

Answer: x = 160
