Hello!
Answer:
n=-9
*The answer must have a negative sign.*
Explanation:
First, you subtract by 7 from both sides of an equation.
![7+2n-7=-11-7](https://img.qammunity.org/2019/formulas/mathematics/middle-school/35edf0xddm4jy1xqjjgzs5sdc961kqq3pn.png)
Then, you simplify.

Next, you divide by 2 from both sides of an equation.
![(2n)/(2)=(-18)/(2)](https://img.qammunity.org/2019/formulas/mathematics/middle-school/2hpg0fieu19fu8ajmwihnepf5ivhwnm3k2.png)
And finally, simplify and solve. You can also dividing into the groups.
