I don't understand how x/7 is 8 because how do you know what x is ???
(x/7) - 3 = 5
Add 3 to both sides.
x/7 = 8
Multiply both sides by 7.
(x/7) * 7 = 8 * 7
x = 56
Proof:
(56/7) - 3 = 5
8 - 3 = 5
Add 3 to both sides.
x/7 = 8
Multiply both sides by 7.
(x/7) * 7 = 8 * 7
x = 56
Proof:
(56/7) - 3 = 5
8 - 3 = 5
