-8x+4y=20 can be simplified to make this easier.

We can divide the numbers all by 2 and get: -4x+2y=10

Now we should put 1 number on one side. Preferably Y.

  • bmmoffattb
So we do this: -2x+y=5 +2x on this side and +2x on the other
bmmoffattb
  • bmmoffattb
As a result, this turns into: =y=2x+5
