Answer 8

In this problem, instead of oranges, you have d^2e.
d is a variable and e is another variable.
You have 42 d^2e - 1 d^2e that leaves 41 d^2e

Sorry. I was looking at the problem and thought it was 42, not 4. I thought the 2 followed the 4, instead of following the d.

4d^2e - d^2e = 4d^2e - 1d^2 = 3d^2e
