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
Answered by bobpursley
(J-22)*3=(R-10)

but J=R originally, so
3R-66=R-10
2R=56
R= ...

(x - 10) = 3(x - 22)
(x - 10) = 3x - 66 | Since 3 times x = 3x and 3 times 22 = 66
x - 3x = 10 - 66
- 2x = - 56
x = 28
