Question

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

Simplify [Q - R] + [S - T].

10m + 5n - 24
10m - 5n + 24
10m + 7n - 14
10m - 7n - 14

Answer 1

Answer:10m + 7n - 14

Steps:

[7m + 3n -(11 - 2m)] + [n + 5 -(-m -3n + 8)]

7m + 3n -11 + 2m + n + 5 + m + 3n - 8

10m + 7n - 14

Answer 2

10m + 7n - 14

Steps:
[7m + 3n -(11 - 2m)] + [n + 5 -(-m -3n + 8)]
7m + 3n -11 + 2m + n + 5 + m + 3n - 8
10m + 7n - 14
