answer:

-m +2n -2

step-by-step explanation:

r - [s + t]

we know   r = 11 - 2m, s = n + 5, and t = -m - 3n + 8.

substituting these values in

11 - 2m - [n + 5 +-m - 3n + 8]

combining like terms

11 - 2m - [n + 5 +-m - 3n + 8]

11-2m - [-2n -m+13]

distributing the negative sign

11-2m +2n +m-13

combine like terms

-2 -m +2n

-m +2n -2
