Answer provided by our tutors
Let 'x' be the first number and 'y' the second then
x = 3*y (one number is thrice the second)
15 + y = x - 17 (fifteen more than the second number is the same as the first number decreased by 17)
By solving the system of equations
x = 3*y
15 + y = x - 17
we find that
x = 48
y = 16
The first number is 48 and the second number is 16.
