\frac{1}{3}x+\frac{1}{3}\left(-6\right)-\frac{1}{5}\left(2x-3\right)=-\frac{4}{15}x
Use the distributive property to multiply \frac{1}{3} by x-6.
\frac{1}{3}x+\frac{-6}{3}-\frac{1}{5}\left(2x-3\right)=-\frac{4}{15}x
Multiply \frac{1}{3} and -6 to get \frac{-6}{3}.
\frac{1}{3}x-2-\frac{1}{5}\left(2x-3\right)=-\frac{4}{15}x
Divide -6 by 3 to get -2.
\frac{1}{3}x-2-\frac{1}{5}\times 2x-\frac{1}{5}\left(-3\right)=-\frac{4}{15}x
Use the distributive property to multiply -\frac{1}{5} by 2x-3.
\frac{1}{3}x-2+\frac{-2}{5}x-\frac{1}{5}\left(-3\right)=-\frac{4}{15}x
Express -\frac{1}{5}\times 2 as a single fraction.
\frac{1}{3}x-2-\frac{2}{5}x-\frac{1}{5}\left(-3\right)=-\frac{4}{15}x
Fraction \frac{-2}{5} can be rewritten as -\frac{2}{5} by extracting the negative sign.
\frac{1}{3}x-2-\frac{2}{5}x+\frac{-\left(-3\right)}{5}=-\frac{4}{15}x
Express -\frac{1}{5}\left(-3\right) as a single fraction.
\frac{1}{3}x-2-\frac{2}{5}x+\frac{3}{5}=-\frac{4}{15}x
Multiply -1 and -3 to get 3.
-\frac{1}{15}x-2+\frac{3}{5}=-\frac{4}{15}x
Combine \frac{1}{3}x and -\frac{2}{5}x to get -\frac{1}{15}x.
-\frac{1}{15}x-\frac{10}{5}+\frac{3}{5}=-\frac{4}{15}x
Convert -2 to fraction -\frac{10}{5}.
-\frac{1}{15}x+\frac{-10+3}{5}=-\frac{4}{15}x
Since -\frac{10}{5} and \frac{3}{5} have the same denominator, add them by adding their numerators.
-\frac{1}{15}x-\frac{7}{5}=-\frac{4}{15}x
Add -10 and 3 to get -7.
-\frac{1}{15}x-\frac{7}{5}+\frac{4}{15}x=0
Add \frac{4}{15}x to both sides.
\frac{1}{5}x-\frac{7}{5}=0
Combine -\frac{1}{15}x and \frac{4}{15}x to get \frac{1}{5}x.
\frac{1}{5}x=\frac{7}{5}
Add \frac{7}{5} to both sides. Anything plus zero gives itself.
x=\frac{7}{5}\times 5
Multiply both sides by 5, the reciprocal of \frac{1}{5}.
x=7
Cancel out 5 and 5.
