Given: Q = 7m + 3n, R = 11 - 2m, S = n + 5, and T = -m - 3n + 8. Simplify R - S + T. m - 2n - 2-m + 2n - 23m - 4n + 14-3m - 4n + 14

Answer:The answer is=-3m-4n+14Step-by-step explanation:Step-by-step explanation: Step 1: Express terms in the form R-S+TWhere R=11-2m, S=n+5, T=-m-3n+8Replace values for R, S and T in R-S+T= (11-2m)-(n+5)+(-m-3n+8) Step 1: Collect all the like termsOpen the brackets 11-2m-n-5-m-3n+8Like terms are similar variables, for example; (-2m, -m) are all like terms since they have a common variable (m) (-n, -3n) are also like terms since they have a common variable (n) (11,-5,8) are constantsStep 2: Solve -2m-m-n-3n+11+8-5=-3m-4n+14 The answer is -3m-4n+14
