Question 409570
find two numbers whose sum is -64, 
if twice the first is one more than the second.
------------------
Equations:
x + y = -64
2x = y+1
----------------
Substitute for "x" and solve for "y":
2(-64-y) = y+1
-128-2y = y+1
3y = -129
y = -43
------
Solve for "x":
x + y = -64
x - 43 = -64
x = -21
