Answer:
B. n = 2
Step-by-step explanation:
Given equation,
[tex]\frac{3}{5}n-\frac{4}{5}=\frac{1}{5}n[/tex]
[tex]\frac{3n-4}{5}=\frac{n}{5}[/tex]
[tex]3n-4=n[/tex]
Subtracting n on both sides,
[tex]3n - 4 - n = n - n[/tex]
[tex]2n - 4 = 0[/tex]
Adding 4 on both sides,
[tex]2n=4[/tex]
Divide both sides by 2,
[tex]n=2[/tex]
Hence, OPTION B is correct.
