Show steps, please! :)

Answer 1

-(2m - 7n) - 3(6m - n)

Expand your negative from the front of the parantheses using the distributive law.

-1(2m - 7n) - 3(6m - n)
= -2m+7n+(-18m) + 3n
= -2m+7n-18m+3n
= -2m-18m+7n+3n
= -20m+10n
= 10n-20m

Sorry if this has confused you, let me know an I will try and clear up any confusion.
