Question

what is the solution to the equation fraction 3 over 5 n minus fraction 4 over 5 equals fraction 1 over 5 n? n = −1 n = 2 n = fraction 5 over 3 n = fraction 5 over 2

Answer 1

3/5n - 4/5 = 1/5n....multiply everything by 5 to get rid of the fractions
3n - 4 = n
-4 = n - 3n
-4 = -2n
-4/-2 = n
2 = n <==

Answer 2

$\frac{3}{5}n- \frac{4}{5} = \frac{1}{5}$n
Putting like terms together;
$\frac{3}{5} n- \frac{1}{5}n= \frac{4}{5}$
$\frac{2}{5} n= \frac{4}{5}$
n=$\frac{4}{5} * \frac{5}{2}$
n=2
