Answer:

2nd option

Step-by-step explanation:

You're goal is to isolate b by itself. The only part you need to worry about is the equation, the rest of the word problem is irrelevant.

The whole process of solving this is to do PEMDAS in reverse.

So first add/subtract all the values that does not have a <em>b</em> attach to it to the other side.

then multiply/divide all the values that is not a <em>b</em> to get the b-value by itself
