Answer:


b > -7

Explanation:

1) Expand.


3b-6b-10 < -3-2b

2) Simplify
3b-6b-10 to
-3b-10.


-3b-10 < -3-2b

3) Add
3b to both sides.


-10 < -3-2b+3b

4) Simplify
-3b-2b+3b to
-3+b.


-10 < -3+b

5) Regroup terms.


-10 < b-3

6) Add 3 to both sides.


-10+3 < b

7) Simplify - 10 + 3 to -7.


-7 < b

8) Switch sides.


b > -7

Thanks,

Eddie

Here's the solution ~


\qquad \sf&nbsp; \dashrightarrow \: 3b - 2(3b + 5) < - 3 - 2b


\qquad \sf&nbsp; \dashrightarrow \: 3b - 6b - 10 < - 3 - 2b


\qquad \sf&nbsp; \dashrightarrow \: - 3b - 10 + 2b + 3 < 0


\qquad \sf&nbsp; \dashrightarrow \: - b - 7 < 0


\qquad \sf&nbsp; \dashrightarrow \: b > - 7
