Explanation:
Right now, we are given: .
is basically b divided by -8. In order to solve for b, we need to "undo" the division part - and to do so, we use the opposite of division, which is multiplication.
So, we would multiply both sides by -8:
On the left, when we multiply by -8, the -8 we multiplied and the -8 in the denominator cancel out, so we're just left with b. On the right side, it's simply the multiplication of -2 by -8. Here, since we have two negative numbers, the negatives cancel out to become a positive product, and 2 * 8 = 16. So, -2 * -8 = 16.
As you did not want the answer, I will not say explicitly the actual answer, but hopefully you can figure it out from my explanation above!
