Question

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

Simplify Q + S - T

Answer 1

replace Q by
\[7m+3n\]
R by
\[11-2m\]
S by
\[n+5\] and T by
\[m-3n+8\] except you can skip R because it is not there

Answer 2

get
\[7m+3n+n+5-(-m-3n+8)\]

Answer 3

remove parentheses using distributive law, then combine like terms. get
\[7m+3n+n+5+m+3n-8\] one more step and you are done

Answer 4
