-20 = x/2 + 7
-20 -7 = x/2 + 7 -7
-27 = x/2
-54 = x
x = -54
because it's math rule
 
        
             
        
        
        
1, 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47
So 16 integers. 
 
        
             
        
        
        
Answer:
Infinite number of solutions
Step-by-step explanation:
when you solve for V, you notice that the term in "v" goes away, and you end up with a true statement: 
2 = 2
This is a true statement no matter what values the variable V has, so it is true for all possible (infinite) values of "v".
