Quizplus · Accepted Answer

To collect like terms, combine the coefficients of like variables and constants: $6m + 6m = 12m$, $-12n + 7n = -5n$, and $-9 + 2 = -7$. This results in $12m - 5n - 7$.

Collect Like Terms −9+6m−12n+6m+7n+2- 9 + 6 m - 12 n + 6 m + 7 n + 2−9+6m−12n+6m+7n+2

Collect Like Terms $- 9 + 6 m - 12 n + 6 m + 7 n + 2$
