I don’t remember the exact answer but here’s the logic.

They gave you an equation, like 2X + Y= 8
In the next equation, they gave you different value for x and y, however both sides were just multiplied by the same number, so it would like like 3(2X+Y)=3(8)
Then all you had to do was figure out what number would make the equation end up creating the same line as the first equation, so that any point on that line is an acceptable value.
