\frac{3}{5}+x=\frac{14\times 3}{15\times 4}-x
Multiply \frac{14}{15} times \frac{3}{4} by multiplying numerator times numerator and denominator times denominator.
\frac{3}{5}+x=\frac{42}{60}-x
Do the multiplications in the fraction \frac{14\times 3}{15\times 4}.
\frac{3}{5}+x=\frac{7}{10}-x
Reduce the fraction \frac{42}{60} to lowest terms by extracting and canceling out 6.
\frac{3}{5}+x+x=\frac{7}{10}
Add x to both sides.
\frac{3}{5}+2x=\frac{7}{10}
Combine x and x to get 2x.
2x=\frac{7}{10}-\frac{3}{5}
Subtract \frac{3}{5} from both sides.
2x=\frac{7}{10}-\frac{6}{10}
Least common multiple of 10 and 5 is 10. Convert \frac{7}{10} and \frac{3}{5} to fractions with denominator 10.
2x=\frac{7-6}{10}
Since \frac{7}{10} and \frac{6}{10} have the same denominator, subtract them by subtracting their numerators.
2x=\frac{1}{10}
Subtract 6 from 7 to get 1.
x=\frac{\frac{1}{10}}{2}
Divide both sides by 2.
x=\frac{1}{10\times 2}
Express \frac{\frac{1}{10}}{2} as a single fraction.
x=\frac{1}{20}
Multiply 10 and 2 to get 20.
