The answer is

First, we need to simplify the equation in parentheses
So we multiply (2n+4) by -2 which will get us -4n-8.
The equation now is

Now we isolate the variable
Lets add the 8 to both sides of the equation
-4n-8+8=10+8
You will get -4n=18
Now divide -4n with -4 and divide 18 with -4 to "isolate the variable"
You would get n=18/-4
Simplify 18/-4 and you would get

N=
