Answer:
[tex]\Huge \boxed{V=1}[/tex]
Step-by-step explanation:
To solve this problem, first you have to isolate it by the v on one side of the equation.
First, add 19 from both sides.
[tex]\displaystyle -19+12v+19=-7+19[/tex]
Solve.
[tex]\displaystyle -7+19=12[/tex]
[tex]\displaystyle 12v=12[/tex]
Next, divide by 12 from both sides.
[tex]\displaystyle \frac{12v}{12}=\frac{12}{12}[/tex]
Last but not least, solve.
[tex]\displaystyle 12\div12=\boxed{1}[/tex]
As a result, the correct answer is v=1.
