You have to set the expressions equal to each other since they're vertical angles, so its 4x+7=5(x-4) then you get 4x+7=5x-20 you then subtract 4x to get 7=x-20 then after add 20 on both sides to get 27=x.

So, lets convert 30% to a fraction, 3/10 which is easier to work with.

All you have to do now is get out a calculator and do 248 *3/10 (or .3) and get 74.4
