The sum of three numbers is 93. The second number is 2 times the third. The first number is 9 more than the third. What are the numbers?
======================
x = 1st number
y = 2nd number
z = 3rd number
---
x = z + 9
y = 2z
x + y + z = 93
-------
x + y + z = 93
Sub for y
x + 2z + z = 93
x + 3z = 93
-----
Sub for x
x = z + 9
z + 9 + 3z = 93
z = 21
etc
