Answer:
n = -1
Step-by-step explanation:
So first subtract 9 to both sides
8n = -n - 9
Now you want the n on one side and the constant on the other
so add the single n to the n side
9n = -9
Divide 9 to both sides to solve for n
n = -1
You are implying that 2x- 9=31
Add 9:
2x=40
Divided by :2
x=20
therefore I thing the number is 20
