Answer:
Step-by-step explanation:
7) 7c +24 - 19 + 5c - 2c
The unknown term is c. We would rearrange the expression such that all the terms containing c are together and simplified and all the constants are also to together. It becomes.
7c + 5c - 2c + 24 - 19
= 10c + 5
= 5(2 c + 1)
8) 9f - 4f - 17 + 10 - 2f
We would collect the like terms. Terms containing the unknown, f would be made to stand together while the constant will also be together. It becomes
9f - 4f - 2f - 17 + 10
3f - 7
