The answer is b = -3.2.
First, you have to add 4 and 10 together to get 14. Then, you subtract 14 from 14 and negative 2. You will get negative 16 because since the 2 is already a negative, you would just be adding two negatives. Next, the equation should look like this: 5b = -16. Now, you would divide by 5 on each side and your answer should be b = -3.2. Hope this helps!
