    Step-by-step explanation:

    3x+4y=-23 ... (1)

    x=3y+1 ... (2)

    Putting (2) in (1)

    3 (3y + 1) + 4y = - 23

    9y + 3 + 4y = - 23

    9y + 4y = - 23 - 3

    13y = - 26

    y = - 26/13

    y = - 2

    Putting y into (2)

    x=3y+1

    x = 3 (-2) + 1

    x = - 6 + 1

    x = - 5
