Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
8x + 11y = -50
-32x – 44y = -200
8x + 11y = -50
-32x – 44y = -200

multiply first equation by 4
+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.

Well, 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.
