Answer:
Step-by-step explanation:
- Apply the distributed property, so it now looks like this: -3n + -18 + 10 = -9
- Combine like terms: -3n + -8 = -9
- Simplify: -3n - 8 = -9
- Add 8 to each side, so it now looks like this: -3n = -1
- Divide each side by -3 to cancel out the -3 next to n. It should now look like this: n = 1/3
I hope this helps!
