Question

Solve:
2(−n−3)−7(5+2n)

2 Answer

  • Answer:

    −16n−41

    Explanation

    Distribute:

    =(2)(−n)+(2)(−3)+(−7)(5)+(−7)(2n)

    =−2n+−6+−35+−14n

    Combine Like Terms:

    =−2n+−6+−35+−14n

    =(−2n+−14n)+(−6+−35)

    =−16n+−41

  • Answer:

    -16n-41

    Step-by-step explanation:

    2(-n-3)-7(5+2n)

    First begin by expanding the bracket.  That is, multiplyingthe brackets by 2 and -7 appropriately.

    In  doing so we have,

    2(-n) x 2(-3) -7(5) x -7 (+2n)

    simplifying becomes:

    -2n-6-35-14n

    collwct like terms becomes -2n-14n-6-35

    Final answer becomes Thus: -16n-41
