Question

Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8.

Simplify Q - [R + S] - T.

A. 10m + 5n - 24
B. 10m - 5n + 24
C. 10m + 7n - 14
D. 10m - 7n - 14

Answer 1

Q - [R + S] - T
7m + 3n - (11 - 2m + n + 5) - -m -3n + 8
7m + 3n - (16 - 2m + n) + m - 3n + 8
7m + 3n - 16 - 2m + n + m - 3n + 8
10m + n - 8

That's the only answer I can come up with. Did you mistype the question or am I wrong with something?

Answer 2

Substitute the corresponding letter with is corresponding value into your original equation and solve or as they say "Plug and Chug!"

Answer 3

Also do not forget the rules for multiplying negatives and positives
That is why @jcpd910 is incorrect
