7 / (x-3) = 1
(x-3) ((7 / (x-3)) = 1 (x-3) multiply both sides by (x-3), (x-3) on the left is cancelled
7 = x-3
3+7 = x - 3 + 3 add both sides by 3, 3 on the right is cancelled
x = 11
x=10, first you have to multiply 7 over to the 1, then it turns into x-3=7, then to Getz by itself you add 3 to 7 to get x=10
