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

    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.
