Answer:
[tex]V=1[/tex]
Step-by-step explanation:
To simplify [tex]V-10=-9[/tex]
We add 10 to both sides of the equation to get:
[tex]V-10+10=-9+10[/tex]
This will simplify to:
[tex]V+0=10-9[/tex]
This simplifies to:
[tex]V=1[/tex]
Therefore the equation has a unique solution, which is:
[tex]V=1[/tex]
