ANSWER:
v = 3 is only a solution to equations 1 and 5.
STEP-BY-STEP EXPLAINATION:
Equation 1:





Therefore, v = 3 is a solution.
Equation 2:





Therefore, v = 3 is not a solution.
Equation 3:




Therefore, v = 3 is not a solution.
Equation 4:





Therefore, v = 3 is not a solution.
Equation 5:





Therefore, v = 3 is a solution.
