Answer:

  • 10m + 7n - 14

Step-by-step explanation:

Given

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

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

  • (7m + 3n - (11 - 2m)) + (n + 5 - (-m - 3n + 8)) =
  • 7m + 3n -11 + 2m + n + 5 + m + 3n - 8 =
  • m(7 + 2 + 1) + n(3 + 1 + 3) - 14 =
  • 10m + 7n - 14
