For this question you can just divide the both sides by -7 so you gonna have :
-7b/-7 = -42/-7 ⇒ b = 6 :)))
i hope this is helpful

(-4/7)(m)=-1
m=7/4
(f o g)^-1 (5) means that you take f of g(x), f(g(x)), and then find the inverse of that function by switching the x and ys, and then solving the equation for x = 5
