    Answer: x = 4, y = 5

    Step-by-step explanation:

    To solve by elimination, we must first eliminate one of the variables of the equations. We'll get rid of y, and to do this, you have to multiply 2x - y = 3 by - 6.

    -6 (2x - 7 = 3)

    -12x + 6 = - 18

    Now add - 12x + 6 = - 18 to with 9x - 6y = 6 to get rid of y.

    -3x = - 12 Solve for x

    x = 4

    Now plug x back into the original equation to solve for y.

    2 (4) - y = 3

    8 - y = 3

    -y = - 5

    y = 5

    Your final solution is (4, 5)
