    Answer:

    x=2, y = 7.

    As an ordered pair the solution is (2, 7).

    Step-by-step explanation:

    5x – 6y = -32

    3x + 6y = 48​

    Adding the 2 equations, we eliminate the terms in y:

    8x +0 = 16

    x = 16/8 = 2.

    Now substitute x = 2 in the first equation:

    5(2) – 6y = -32

    10 + 32 = 6y

    6y = 42

    y = 7.
