Answer:
the answer is b) 3N/5
Explanation:
The questions says that 3N = 5.
For obtain the answer, we need that one side of the equation becomes equal to 1.
the way to achieve that situation is to divide by 3N or by 5 all the equation:
Case 1. Divide by 3N
If divide all the terms in the initial equation by 3N, it gets:
3N=5


However this solutions is not in the multiple choice answers.
Case 2. Divide by 5
If divide all the terms in the initial equation by 3N, it gets:
3N=5


It also can be writing as

Then, the correct answer is 1 = 3N/5
