Answer 1

Answer:

Step-by-step explanation:

Given that,

9b + 5 = 4 ( b - 2 ) + 8

⇒ 9b + 5 = 4b - 8 + 8

⇒ 9b + 5 = 4b

⇒ 9b - 4b = - 5 ( ∵transposing )

⇒ 5b = - 5

⇒ b = -5 / 5

⇒ b = - 1 is the answer.

Answer 2

b = -1

Step-by-step explanation:

Given in the question

9b + 5 = 4*(b-2) + 8

9b + 5 = 4b - 8 + 8

9b - 4b = -5
