Answer provided by our tutors
let
x = the number of marbles the first boy has
y = the number of marbles the second boy has
One boy has 5 times as many marbles as a second boy
x = 5y
If the first were to give 18 marbles to the second,each would then have the same amount:
x - 18 = y + 18
by solving the system of equations:
x = 5y
x - 18 = y + 18
we find:
x = 45 marbles
y = 9 marbles
