\frac{4}{5}\times 4n+\frac{4}{5}\left(-2\right)=-\frac{2}{3}\left(n+3\right)
Use the distributive property to multiply \frac{4}{5} by 4n-2.
\frac{4\times 4}{5}n+\frac{4}{5}\left(-2\right)=-\frac{2}{3}\left(n+3\right)
Express \frac{4}{5}\times 4 as a single fraction.
\frac{16}{5}n+\frac{4}{5}\left(-2\right)=-\frac{2}{3}\left(n+3\right)
Multiply 4 and 4 to get 16.
\frac{16}{5}n+\frac{4\left(-2\right)}{5}=-\frac{2}{3}\left(n+3\right)
Express \frac{4}{5}\left(-2\right) as a single fraction.
\frac{16}{5}n+\frac{-8}{5}=-\frac{2}{3}\left(n+3\right)
Multiply 4 and -2 to get -8.
\frac{16}{5}n-\frac{8}{5}=-\frac{2}{3}\left(n+3\right)
Fraction \frac{-8}{5} can be rewritten as -\frac{8}{5} by extracting the negative sign.
\frac{16}{5}n-\frac{8}{5}=-\frac{2}{3}n-\frac{2}{3}\times 3
Use the distributive property to multiply -\frac{2}{3} by n+3.
\frac{16}{5}n-\frac{8}{5}=-\frac{2}{3}n-2
Cancel out 3 and 3.
\frac{16}{5}n-\frac{8}{5}+\frac{2}{3}n=-2
Add \frac{2}{3}n to both sides.
\frac{58}{15}n-\frac{8}{5}=-2
Combine \frac{16}{5}n and \frac{2}{3}n to get \frac{58}{15}n.
\frac{58}{15}n=-2+\frac{8}{5}
Add \frac{8}{5} to both sides.
\frac{58}{15}n=-\frac{10}{5}+\frac{8}{5}
Convert -2 to fraction -\frac{10}{5}.
\frac{58}{15}n=\frac{-10+8}{5}
Since -\frac{10}{5} and \frac{8}{5} have the same denominator, add them by adding their numerators.
\frac{58}{15}n=-\frac{2}{5}
Add -10 and 8 to get -2.
n=-\frac{2}{5}\times \frac{15}{58}
Multiply both sides by \frac{15}{58}, the reciprocal of \frac{58}{15}.
n=\frac{-2\times 15}{5\times 58}
Multiply -\frac{2}{5} times \frac{15}{58} by multiplying numerator times numerator and denominator times denominator.
n=\frac{-30}{290}
Do the multiplications in the fraction \frac{-2\times 15}{5\times 58}.
n=-\frac{3}{29}
Reduce the fraction \frac{-30}{290} to lowest terms by extracting and canceling out 10.
