    x=2, y=-3

    Step-by-step explanation:

    y=x-5 ... (1)

    5x+2y=4 ... (2)

    Let's substitute (1) into (2)

    5x+2 (x-5) = 4

    5x+2x-10=4

    7x-10=4

    Add 10 to both sides

    7x=14

    Divide both sides by 7

    x=2

    Substitute the value for x into (1)

    y=x-5

    y=2-5

    y=-3

    Therefore x is 2, y is-3

    x = 2, y = - 3

    Step-by-step explanation:

    y = x - 5

    5x + 2y = 4

    5x + 2 (x - 5) = 4

    5x + 2x - 10 = 4

    7x = 14

    x = 2

    y = 2 - 5

    y = - 3
