Question

8 - y = x
How to do this please

Answer 1

you have to get 8 on the other side. so what you do is you subtract by 8 on both sides. that cancels out the 8 on the left side and allows you to move it to the other side. after that you still have a negative y so you divide everything by -1 which will give you your answer

Answer 2

8 - y = x Subtract 8 from both sides
-y = x - 8 Divide both sides by -1
y = -x + 8
