    x = 22/7

    y = - 3/7

    Step-by-step explanation:

    X = 2y + 4

    3 (2y + 4) + y = 9

    6y + y = 9 - 12

    7y = - 3

    y = -3/7

    By using the first equation we will find the value of X:

    x - 2y = 4 where y = - 3/7

    x - 2 (-3/7) = 4

    x + 6/7 = 4

    x = 4 - 6/7

    x = 22/7
