Solve 14-x = 4(1+x)

First of all we want to expand the brackets out. We do this by mulitplying 4 by each number in the bracket. This then gives us 14-x = 4+4x. We then want to get all the x's on one side and the numbers on the other, rembering that we need to the same thing to sides. If we add an x to both sides then it'll disappear on the left but they'll be an extra one on the right. Giving us 14=4+5x. Then we do the same thing to get only numbers on the other side, so we take away 4 from the right, but we also have to do this to the left side too leaving us with 10 = 5x. To find what x is, we then divide by the number next to it and again do this to both sides, dividing by 5 then gives us the answer of x=2
