Question

Solve:
2(−n−3)−7(5+2n)

Answer 1

−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 2

-16n-41

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
