    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
