1)
x/4 - 3 = 2
x/4 = 2 + 3
x = 4(5)
x = 20

2)
(x - 3)/4 = 2
x - 3 = 4(2)
x = 8 + 3
x = 11

The answer to one of them is 20 and the other 11.
I'll leave you to work out which is which!

In all honesty, if you can't even TRY to answer this level of problem, I don't think you should be in this class.
