    The answer is - 3m-4n+14

    Step-by-step explanation:

    Simplify R-S+T

    Step 1: Replace for R, S and T

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

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

    Step 2: Open the brackets

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

    Step 3: Collect the like terms

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

    Solving for each group

    (-3m), (-4n), (14)

    Step 4: Add up all the terms

    The answer is - 3m-4n+14
