Answer:

b = -2

Explanation:

30 = -5(6b+6)

30 = -30b - 30

60 = -30b

b = -60 : 30

b = -2

Answer:


\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}


30 = - 5(6b + 6)

let's simplify the parenthesis first ~


30 = - 30b - 30

now , bring the like terms at one side of the equation !


- 30b = 30 + 30


- 30b = 60

dividing both sides of the equation by 30 ,


\\ \frac{ - \cancel{30}b}{\cancel{30}} = \cancel(60)/(30) \\


\dashrightarrow \: - b = 2 \\ \\ \dashrightarrow \: b = - 2

hope helpful :)
