\frac{4}{10}\left(x+3\times \frac{3}{10}\right)=\frac{8}{10}
Cancel out 9 on both sides.
\frac{2}{5}\left(x+3\times \frac{3}{10}\right)=\frac{8}{10}
Reduce the fraction \frac{4}{10} to lowest terms by extracting and canceling out 2.
\frac{2}{5}\left(x+\frac{3\times 3}{10}\right)=\frac{8}{10}
Express 3\times \frac{3}{10} as a single fraction.
\frac{2}{5}\left(x+\frac{9}{10}\right)=\frac{8}{10}
Multiply 3 and 3 to get 9.
\frac{2}{5}x+\frac{2}{5}\times \frac{9}{10}=\frac{8}{10}
Use the distributive property to multiply \frac{2}{5} by x+\frac{9}{10}.
\frac{2}{5}x+\frac{2\times 9}{5\times 10}=\frac{8}{10}
Multiply \frac{2}{5} times \frac{9}{10} by multiplying numerator times numerator and denominator times denominator.
\frac{2}{5}x+\frac{18}{50}=\frac{8}{10}
Do the multiplications in the fraction \frac{2\times 9}{5\times 10}.
\frac{2}{5}x+\frac{9}{25}=\frac{8}{10}
Reduce the fraction \frac{18}{50} to lowest terms by extracting and canceling out 2.
\frac{2}{5}x+\frac{9}{25}=\frac{4}{5}
Reduce the fraction \frac{8}{10} to lowest terms by extracting and canceling out 2.
\frac{2}{5}x=\frac{4}{5}-\frac{9}{25}
Subtract \frac{9}{25} from both sides.
\frac{2}{5}x=\frac{20}{25}-\frac{9}{25}
Least common multiple of 5 and 25 is 25. Convert \frac{4}{5} and \frac{9}{25} to fractions with denominator 25.
\frac{2}{5}x=\frac{20-9}{25}
Since \frac{20}{25} and \frac{9}{25} have the same denominator, subtract them by subtracting their numerators.
\frac{2}{5}x=\frac{11}{25}
Subtract 9 from 20 to get 11.
x=\frac{11}{25}\times \frac{5}{2}
Multiply both sides by \frac{5}{2}, the reciprocal of \frac{2}{5}.
x=\frac{11\times 5}{25\times 2}
Multiply \frac{11}{25} times \frac{5}{2} by multiplying numerator times numerator and denominator times denominator.
x=\frac{55}{50}
Do the multiplications in the fraction \frac{11\times 5}{25\times 2}.
x=\frac{11}{10}
Reduce the fraction \frac{55}{50} to lowest terms by extracting and canceling out 5.
