    You cannot eliminate x and end up with two different equations.

    5x+3y=9.. B

    2x-4=40…A

    Solve A for x.

    2x – 4 = 40

    2x = 40 + 4

    2x = 44

    x = 44/2

    x = 22

    The only thing I can think of doing is to plug 22 into B.

    5(22) + 2y = 9

    110 + 2y = 9…This leads to an answer for y.

    No two NEW EQUATIONS is possible.

    2y = 9 – 110

    2y = -101

    y = -101/2

    Check your question again.
