Answer 4

yep!

Answer 5

k, assuming it it...
just remember to always balance the 2 sides of your equation
so LHS /2 = RHS /2

2 x cubed root of (7b-1) = 4
2 x cubed root of (7b-1) /2 = 4 /2
cubed root of (7b-1) = 2

now cube both sides (^3), so
cubed root of (7b-1) = 2
cubed root of (7b-1) ^3 = 2 ^3
(7b-1) = 8

can u take it from here?
