Answer provided by our tutors
Let
x = the first number
y = the second number
One number is 5 less than a second number:
x = y - 5
Twice the second number is 8 less than 5 times the first:
2y = 5x - 8
We have the following system of equations:
x = y - 5
2y = 5x - 8
........
........
x = 6
y = 11
The two numbers are 6 and 11.
