Answer:

The answer is -3m-4n+14

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
