Which expression is equivalent to -3(2m-1)-n 6m-n-3 6m-n+3 -6m-n-3 -6m-n+3

-6m -n +3

by order of operations
-3(2m-1)-n=-6m+3-n=-6m-n+3

Let's simplify step-by-step.−3(2m−1)−n
Distribute:= (−3)(2m)+(−3)(−1)+−n=− 6m  + 3 + −n
D=  −6m − n  +3

B).  -3(2m-1)-n Final result : -6m - n + 3 Step by step solution : Step  1  :Equation at the end of step  1  : (0 - 3 • (2m - 1)) - n Step  2  : Step  3  :Pulling out like terms : 3.1     Pull out like factors :

   -6m - n + 3  =   -1 • (6m + n - 3) 
Final result : - 6m - n + 3

Iknow one of the answers is a and maybe b but not 100% sure about b
