Question

Juan and Rachel have the same number of marbles. Rachel gives away 10 marbles and Juan gives away 22 marbles. Rachel then has 3 times as many marbles as Juan. How many marbles did each of them have at first

Answer 1

Let, the number of marbles =x.(for both juan and Rachel).

x = x

x-10 = 3(x-22)

x-10=3x-66

66-10 = 3x-x

2x =56

x=28
