Answer 4

\[3/5n - 4/5 = 1/5n\]
Flip everything
\[5n/3-5/4=5n\]
Subtract 5n/3 from both sides
\[-5/4=5n-5n/3\]
Multiply the "5n" by 3 so that you can subtract
\[-5/4=15n/3 - 5n/3\]
Subtract
\[-5/4=10n/3\]
Multiply both sides by 3
\[-15/4=10n\]
Divide both sides by 10
\[n=-15/40\]
simplify
\[n=-3/8\]

Answer 5

ok

Answer 6

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 7

which option is it B or A?

Answer 8

n=1/2\[\text{Expand}\left[5 n \left(\frac{3}{5 n}-\frac{4}{5}\right)=\frac{5 n}{5 n}\right] \]\[3-4 n=1 \]\[4 n=2 \]\[n\to \frac{1}{2} \]

Answer 9

whoops, robtobey is right but that isn't an answer?

Answer 10

n = 1/2\[\left\{\frac{3-4 n}{5 n},\frac{1}{5 n}\right\}\text{/.}\, n\to \frac{1}{2} \]\[\left\{\frac{2}{5},\frac{2}{5}\right\} \]

Answer 11

-> is a Mathematica operator that means the LHS can be replaced by the RHS .
