Answer:
The answer is the picture down below. Hope this helps :)
Step-by-step explanation:
Step 1: -9+n=-18. You would add the inverse to both sides, meaning you’d add nine to the negative nine to cancel it out and then then 9 to -18.
-9+n=-18
+9 +9
That would leave you with the equation: n=-9, since -18 plus a positive 9 equals a negative nine. You’re final answer is n= -9.
You can check you answer by substituting the variable with the solution (-9).
-9 + -9= -18
