Given: q = 7m + 3n, r = 11 - 2m, s = n + 5, and t = -m - 3n + 8.

simplify r - s + t.

a.) m - 2n - 2
b.) -m + 2n - 2
c.) 3m - 4n + 14
d.) -3m - 4n + 14

Option D is correct

-3m -4n +14

Step-by-step explanation:

Given:

Q = 7m + 3n,

R = 11 - 2m,

S = n + 5, and

T = -m - 3n + 8.  

We have to Simplify R-S+T

R -S +T = 11 - 2m - (n+5) + (-m -3n +8) = 11 - 2m-n-5-m-3n+8

Combine Like terms we have;

R -S +T = -3m -4n +14

Therefore, the Simplification of R -S +T is, -3m -4n +14
