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

R - [S + T]

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

= 11 - 2m - (-2n - m + 13)

= 11 - 2m + 2n + m - 13

= -2 - m + 2n

R - [S + T]

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

= 11 - 2m - (-2n - m + 13)

= 11 - 2m + 2n + m - 13

= -2 - m + 2n

R-(S+T)

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

=11-2m+2n+m-13

=-m+2n-2

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

=11-2m+2n+m-13

=-m+2n-2
