3/4n=9 how do you get the answer?

Question

I don't understand how to get the answer, please I need help.!!!!

Answer 1

Student,

 

I am not sure if you meant

 

3/(4n) = 9

 

or

 

(3/4)n = 9

 

Lauren solved the first case.  If you meant the second case,

 

Multiply both sides by 4/3.

 

n = (4/3)(9) = 36/3 = 12

 

 

Answer 2

3/4n=9

 

Multiply both sides by 4n

 

3 = 36n

 

n = 3/36 = 1/12
