    b = - 5

    Step-by-step explanation:

    -10 (10+b) = 5 (3b+5)

    Distribute

    -100 - 10b = 15b + 25

    Add 10b to each side

    -100-10b+10b = 15b+10b + 25

    -100 = 25b+25

    Subtract 25 from each side

    -100-25 = 25b+25-25

    -125 = 25b

    Divide by 25

    -125/25 = 25b/25

    -5 = b
