Could someone me solve this problem?

Hello!

n=-9

*The answer must have a negative sign.*

Step-by-step explanation:

First, you subtract by 7 from both sides of an equation.

Then, you simplify.

Next, you divide by 2 from both sides of an equation.

And finally, simplify and solve. You can also dividing into the groups.

Hope this helps!
