let the larger be x
let the smaller be 20-x
Now just translate ...
three times the larger ---> 3x
twice the smaller ---> 2(20-x)
that "difference" is 40
3x - 2(20-x) = 40
3x - 40 + 2x = 40
5x = 80
x = 16
the larger is 16
(the smaller is 4)
How do I set this up and how do I solve:
The sum of two numbers is 20 The difference between 3 times the larger number and twice the smaller number is 40. What is the larger number?
