Answer:
-13
-
+ 4p + 3
Step-by-step explanation:
I am having a little trouble reading the number. I think 5 is the question number and not part of the problem. I think this is the problem:
(4p - 6
- 3) - (8
+ 7
- 6) You take the opposite of everything inside the second set of parentheses. You can think of it as multiplying through by -1
4p - 6
- 3 - 8
- 7
+ 6 Now we combine like terms. That is the numbers with the same variable p and the same power of p.
-13
- 8
+ 4p + 3

They are represented by letters. Usually ( but not necesserally) the letters at the end of the alphabet like x,y and z.
