The sum of two numbers is 4 less than twice the larger. If the larger is decreased by three times the smaller, the result is -20. Find the numbers.
-----
Equations:
x + y = 2x-4
x -3y = -20
-----
Rearrange:
x - y = 4
x -3y =-20
--------------------
Subtract and solve for "y":
2y = 24
y = 12
---
Solve for "x":
x - y = 4
x -12 = 4
x = 16
