    Distribute -5 into the parentheses, you get
    (-10y+40)-3(1+x)-7
    Distribute -3, you get
    -10y+40-3+3x-7
    Combine like terms, the only like terms are 40, -3, and -7 which gives you 30
    The equation is now
    -10y+30-3x

    -(2y-8)-3(1+x)-7
    -10y+40-3(1-x)-7
    -10y+40-3-3x-7
    -10y+30-3x
