b=5

Explanation:

Let's take the equation in steps. We want to isolate b.

Looking at the equation, we want to first divide by 8.

240/8=(8(7b-5))/8

30=7b-5

Now, let's add 5 to both sides. Remember, we're trying to get b b itself, so we try to remove numbers from that side.

30+5=(7b-5)+5

35=7b

Now, we can simply divide both sides by 7 to get:

35/7=(7b)/7

b=5
