8x + 11y = -50

-32x – 44y = -200

+32 x + 44 y = -200

-32 x - 44 y = -200

multiply second equation by -1

+32 x + 44 y = -200

+32 x + 44 y = +200

These are two parallel lines. They never intersect. There is no solution.

**Damon**, Wednesday, August 10, 2011 at 6:01pmWell, say x + y = 1

and x + y = 2

that is impossible. There is no single point where x+y = two different numbers.

If you graph those two lines, you will see that they are parallel to each other and never cross.
