Answer:
We cannot solve without a value for x. The simplified form is 
Step-by-step explanation:
If the equation is
then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

Answer:
v= -2
Step-by-step explanation:
2v + 7 = 3
(-7 both sides)
2v = -4
(divide bu 2 on both sides)
