I pretty sure Jimmyrep answer is right. I came to the same result using same steps

Answer 8

Jimmy rep is correct. I just worked it out and got -3.

Here's my steps along with an explanation:

5(b+2)+5b=-20 (original equation)
5b + 10 + 5b = -20 (distributed the 5 to the b and to the 2)
10b + 10 = -20 (combined the b's)
10b = -30 (subtracted 10 from both sides)
b=-3 (divided both sides by 10)
