Question 330010: The sum of three numbers is -48 the first is 12 more than the second number, and the third number is 20 less than twice the second number find the three numbers Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! The sum of three numbers is -48
x + y + z = -48
----------------------
the first is 12 more than the second number
x = y+12
-------------------
the third number is 20 less than twice the second number
z = 2y-20
-------------------
find the three numbers
================================
Substitute for x and z and solve for "y":
y+12 + y + 2y-20 = -48
-----
4y - 8 = -48
4y = -40
y = -10
-------------------------------
Since x = y+12, x = 2
---
Since z = 2y-20 = -40
