    The order paired (-1, 3) is the solution

    Step-by-step explanation:

    ∵ y = 5x + 8

    ∵ y = - 4x - 1

    ∴ 5x + 8 = - 4x - 1

    ∴ 5x + 4x = - 1 - 8

    ∴ 9x = - 9

    ∴ x = - 1

    Substitute x in any of the two equation to find the value of y

    ∴ y = 5 (-1) + 8 = - 5 + 8 = 3

    ∴ The ordered pair is (-1, 3)
