Answer

-2, 6

Work Step by Step

For $n+2=-9$, I would add -2 to both sides. Adding -2 to both sides would give us $n+2-2=n$ on the left side. This would isolate the variable on one side. For $10=b-6$, I would add 6 to both sides. Adding 6 to both sides would give us $b-6+6=b$ on the right side. This would isolate the variable on one side.
