How do I rearrange and make y the subject in equations such as "(y/4) - X = 1"?

The aim is to finish with an equation that looks like "y = .....". We want Y and X on separate sides.The main thing to remember is that whatever you do to one side of the equation, you also do to the other. For example, you could times the left side of any equation by 2, as long as you also do that to the right side. In this example, we want to end up with "y=" so the first thing we want to do is move the "x" to the other side. To do this, look at the left side. What could you do to make the X disappear? If you added 1X then the equation would become "(y/4) = 1+X". Now we're nearly there. The next thing to do is to multiply by 4, which gives you "y = 4(1+X)". You could also write the answer as " y = 4 + 4X".
