    Answer:

    x = 2

    y = 3

    Step-by-step explanation:

    x = 2y – 4

    5x – 6y = -8

    Substitute for x.

    5(2y – 4) – 6y = -8

    10y – 20 – 6y = -8

    4y – 20 = -8

    4y = -8 + 20

    4y = 12

    y = 12 รท 4

    y = 3

    x = 2y – 4

    x = 2(3) – 4

    x = 6 – 4

    x = 2
