The sum of three numbers is 4. The first, minus the second, plus 4 times the third, is -9. The third, plus 5 times the first, plus the second, is 24. What are the numbers?
------------
Let the numbers be x, y, and z.
Three equations:
x + y + z = 4
x - y + 4z = -9
5x + y + z = 24
----------------
Solve by whatever method you know.
I get:
x =5
y =2
z =-3
