1\2n=7 what is N

Question

help if been on this question for hours

Answer 1

1 / (2n) = 7

1 / (2n) = 7 / 1

2n / 1 = 1 / 7         reciprocals of equals are equal

n = 1 / 14              divide both sides by 2

Answer 2

I assume you meant 

 

1 / (2n) = 7  [please use parentheses], and that you want n, not N.

 

Multiply both sides by n and get

 

1/2 = 7n

 

Divide both sides by 7 and get

 

n = 1/14
