    Answer:

    x = 0

    y = -5

    Step-by-step explanation:

    Since you already have the value of y, all you need to do is plug it into the equation, like so:

    5x + 4y = -20

    5x + 4(-5) = -20

    5x – 20 = -20

    Add 20 to both sides:

    5x – 20 = -20

        + 20  + 20

    ___________

    5x = 0

    Finally, divide both sides by 5:

    5x = 0

    x = 0

    So now you have, x = 0 and y = -5

    Step-by-step explanation:

    If y = – 5

    Then put value of y

    5x + 4(-5) = – 20

    5x – 20 = – 20

    5x = – 20 + 20

    5x = 0

    x = 0
