\frac{6}{15}+\frac{5}{15}+\frac{1}{6}+\frac{10}{1}=x
Least common multiple of 5 and 3 is 15. Convert \frac{2}{5} and \frac{1}{3} to fractions with denominator 15.
\frac{6+5}{15}+\frac{1}{6}+\frac{10}{1}=x
Since \frac{6}{15} and \frac{5}{15} have the same denominator, add them by adding their numerators.
\frac{11}{15}+\frac{1}{6}+\frac{10}{1}=x
Add 6 and 5 to get 11.
\frac{22}{30}+\frac{5}{30}+\frac{10}{1}=x
Least common multiple of 15 and 6 is 30. Convert \frac{11}{15} and \frac{1}{6} to fractions with denominator 30.
\frac{22+5}{30}+\frac{10}{1}=x
Since \frac{22}{30} and \frac{5}{30} have the same denominator, add them by adding their numerators.
\frac{27}{30}+\frac{10}{1}=x
Add 22 and 5 to get 27.
\frac{9}{10}+\frac{10}{1}=x
Reduce the fraction \frac{27}{30} to lowest terms by extracting and canceling out 3.
\frac{9}{10}+10=x
Anything divided by one gives itself.
\frac{9}{10}+\frac{100}{10}=x
Convert 10 to fraction \frac{100}{10}.
\frac{9+100}{10}=x
Since \frac{9}{10} and \frac{100}{10} have the same denominator, add them by adding their numerators.
\frac{109}{10}=x
Add 9 and 100 to get 109.
x=\frac{109}{10}
Swap sides so that all variable terms are on the left hand side.
