Question

-b-(13+4b)=-3(5-9b)+2

Answer 1

Here you to first open the bracket by multiple with the sign and number next to it. after that u have to take b to one side and number to other side.

when you will take it, the minus will become + and vice versa

Explanation:

-b- 13- 4b = -15 + 27b+ 2

3b-13 = 27b-13

-13+13 = 27b-3b

0=24b

b = 0
