Given:
![-2=n+10](https://img.qammunity.org/2019/formulas/mathematics/middle-school/sf72z7ae45004ex8cp7h9zsr2dtuqjtdwy.png)
To solve, we need to get n isolated on one side. To do this, subtract 10 from both sides. This will cancel the +10 on the right side and give us -12 of the left, leaving us with:
or
![n=-12](https://img.qammunity.org/2019/formulas/mathematics/middle-school/psbkmjhhjb4qj6aq48i7o3rkjcn9anp6to.png)
If you want to check your answer, plug in -12 for n.
![-2=-12+10](https://img.qammunity.org/2019/formulas/mathematics/middle-school/o7bc8q0x8ejqbj3omypuyhd54q086e0cl7.png)
![-2=-2](https://img.qammunity.org/2019/formulas/mathematics/middle-school/4cnqp7fl33nw2hy32v49ldqrck7boev1fn.png)
The statement is true, therefore,
