Answer:
n= -1/3
Step-by-step explanation:
To find non permissible values (npv), focus on the denominator of an expression
In this case, the denominator is: (3n+1)
The npv is basically the value that would make the expression equal to 0
So, make the expression in the denominator equal 0
3n+1 = 0
Solve for n
3n= -1
n = (-1/3)
Thus, the npv for this equation is n= -1/3
