The sum of three numbers is -4. The second number decreased by the third is equal to the first. The sum of the first and second numbers is -5. Find the numbers.
----
a + b + c = -4
b - c = a
a + b = -5
---------------------
Rearrange::
a + b + c = -4
a - b + c = 0
a + b + 0 = -5
-----------------------
Subtract 1st row from 2nd
Subtract 1st row from 3rd
a + b + c = -4
0 -2b + 0 = 4
0 + 0 - c = -1
------
c = 1
b = -2
---
a -2 +1 = -4
a = -3
