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 .

And if you'MoreAnd we'll get p over r because these would cancel out to give one and that's equal to b. And if you'd like you could write it as b is equal to p over r.

Rearrange the equation so that the unknown variable is by itself on one side of the equals sign (=) and all the other variables are on the other side. RULE #1: you can add, subtract, multiply and divide by anything, as long as you do the same thing to both sides of the equals sign.

And if I multiply both sides by V. Notice that that's how weMoreAnd actually multiply both sides by V. And if I multiply both sides by V. Notice that that's how we get M by itself and I'm left with VD equals M or simply M equals VD.

Solving by rearranging means you are moving the terms in an equation around to find your answer. When solving by rearranging, remember these rules: Use the opposite operation to move terms from one side to the other. Remember to always do the same operation to both sides of your equation.
