    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 : 4

    y = 3

    x = 2y - 4

    x = 2 (3) - 4

    x = 6 - 4

    x = 2
