You can
put this solution on YOUR website!
Let x = the larger number
Let y = the smaller number
You have two variables, so you need two equations:
Equation 1: x-y=16
Equation 2: 5y=2x-8
You can now use elimination or substitution to solve. I will use substitution:
x-y=16
x=16+y
Substitute this into the second equation:
5y=2x-8
5y=2(16+y)-8
5y=32+2y-8
5y=24+2y
3y=24
y=8
Now find x:
x=16+y
x=16+8
x=24
So the two numbers are 8 and 24.
