    What are you trying to find?

    If its just multiply bracket by -5 then:

    -5 * 3x = -15x
    -5 * 9 = -45
    -5 * -7y = 35y

    -15x - 45 + 35y

    what do you want to do? expand it?
    if that is so...
    -5(3x + 9 - 7y)

    so what we do is multiply the -5 into 3x, 9 and -7y. Since it literally means -5 * (3x + 9 - 7y)

    so it will become:
    -15x - 45 + 35y

    (-5 x 3x = -15x) (-5 x + 9 = -45) (-5 x -7y = 35y)
