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

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

c. (3,2,6) is the answer.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
