    Answer: 5x-30 = - 55

    Step-by-step explanation:

    *-10=-15

    Make x the subject

    X=-15+10

    *=-5

    Substitute x=-5 in the equation 5x-30

    5 (-5) - 30

    -25-30

    =-55

    Well, - 5 - 10 is 15 so that makes x - 5.

    5 x - 5 = 25, and 25 - 30 = - 5, making the answer - 5
