Answer: Hi!
First, we should combine like terms:
4b + 5b = 8b − 1 +3b + 15 =
9b = 11b + 14
Now, we should subtract 11b from both sides.
-2b = 14
Now, we should divide both sides by -2.
b = -7
Hope this helps!

Answer:
In December, Zalma will have $480.
Step-by-step explanation:
The time from March to October is 7 months. In those 7 months, she gains $280. So every month, her investment gains $40.
The time from March to December is 9 months. She will gain $360 during that time. We add her initial $120 with the $360, and Zalma will have $480.
It's not confirmed, but it's what I got. :D
We can do this easily using 0s.
(x - i) (x + i) (x + 4) (x - 1) = 0
If you plug in any of the numbers, you'll get 0, making the equation true.
