    Step-by-step explanation:

    So since both equations equal f (x), we can set them equal to each other

    -15x - 13 = - 28

    Our next step is to get x by itself on one side of the equation. To do this, you:

    Add 13 to both sides

    -15x = - 15

    Divide both sides by - 15

    x = 1
