And to get rid of the 3 we justMoreAnd just subtract 4 from both sides. Giving us y minus 4 equals 3x. And to get rid of the 3 we just divide both sides by 3. But importantly it's the whole of the y minus 4 that we're dividing by 3.

Example Rearrange y =11+7x to make x the subject. Solution Starting from y =11+7x we subtract 11 from each side to give y ? 11 = 7x. Then, dividing both sides by 7 gives y ? 11 7 = x. Finally x = y ? 11 7 .
