Answer:

-15-4m-m

Step-by-step explanation:

There is a variable so you are going to be careful.

First you do the distributive property with the parenthesis.

Since there is a negative infront of the two, you multiply everything by that negative number

So -2 times -9 is 18 and -2 times 2m is -4m.

Now your problem should look like this.

3-18-4m=m

Now combine like terms

You should come up with:

-15-4m=m

Since you cannot add anything else you would leave it like that!



So you add 9+2=11 then you do this 3-2(11) then multiply 2×11=22 then do this 3-22=-19
