Peter and James were usually given $58 altogether for their weekly pocket money. As James needed money for new books next week, he asked for $19 more. As a result, he would have 3/4 as much money as Peter. How much was Peter’s pocket money?
james' share --- x
Peter's share ---- 58-x
next week, James has x + 19
x + 19 = (3/4)(58-x)
times 4
4x + 76 = 3(58-x)
