23 computers
the they make 0 dollars
L - Lane's age
m- Mel's age.
Lane is 10 times Mel's age, so 10m = l
difference in their age is 27 so l - m = 27
Substitute l = 10m and you'll have:
10m - m = 27
9m = 27 /:9
m=3
And l = 10m = 10*3 = 30
So Lane has 3 years old and Mel has 30 years old.
4x + 6y = 8z +34
4x+6y - 8z = 34
