Step-by-step explanation:

Hello There!

The whole objective is to isolate the variable

To do so we use inverse operations

so to get rid of the 5 we divide each side by 5

5/5 cancels out

105/5=21

we're left with m=21

C. x=2

Step-by-step explanation:

-3(x-4)=2x+4-x

-3x+12=x+4

+3x     +3x

12=4x+4

-4       -4

8=4x
