Question

What is the simplified form of the equation 3/5n-4/5=1/5n ?

A- n=-1
B- n=2
C- n =5/3
D- n=5/2

Answer 1

3/5=.6
4/5=.8
1/5=.2
The answer is n=-1

Answer 2

B. n = 2

Explanation:

Given equation,

`(3)/(5)n-(4)/(5)=(1)/(5)n`

`(3n-4)/(5)=(n)/(5)`

`3n-4=n`

Subtracting n on both sides,

`3n - 4 - n = n - n`

`2n - 4 = 0`

Adding 4 on both sides,

`2n=4`

Divide both sides by 2,

`n=2`

Hence, OPTION B is correct.
