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

-8m + 7n - 3
-8m - 7n - 3
8m + 7n - 3
8m - 7n - 3

Answers

If you would like to simplify Q + S - T, you can do this using the following steps:

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

Q + S - T = 7m + 3n + n + 5 - (-m - 3n + 8) = 7m + 3n + n + 5 + m + 3n - 8 = 8m + 7n - 3

The correct result would be 8m + 7n - 3.
