Question

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

Simplify [Q - R] + [S - T].


10m + 5n - 24

10m - 5n + 24

10m + 7n - 14

10m - 7n - 14

Answer 1

well first plug in everything, What do you get?

Answer 2

I don't know, that's why I put this on here lol

Answer 3

well okay so ur equatin is (Q-R)+(S-T) Q is 7m+3n put that in for Q and you get (7m+3n -R)+(S-T) Now do the same for R, S, and T

Answer 4

(7m+3n-11-2m)+(N+-(-m-3n+8)) This is what you get

Answer 5

Now just do PEMDAS
