Question

how do i get y by itself with 4x-4y=8

Answer 1

x - y = 2
y = x - 2

Answer 2

First divide each term by four, then add y to both sides while subtracting 2 from both sides to get:

y = x - 2

Answer 3

thankyou both !

Answer 4

Just to warn you, the method will not always be the same. In this case, 4 just happens to be a common factor of itself and 8.
