\frac{7}{3}+\frac{1}{5}-\frac{4}{15}=\frac{4}{5}x\left(\frac{3}{2}+\frac{4}{3}\right)
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
\frac{35}{15}+\frac{3}{15}-\frac{4}{15}=\frac{4}{5}x\left(\frac{3}{2}+\frac{4}{3}\right)
Least common multiple of 3 and 5 is 15. Convert \frac{7}{3} and \frac{1}{5} to fractions with denominator 15.
\frac{35+3}{15}-\frac{4}{15}=\frac{4}{5}x\left(\frac{3}{2}+\frac{4}{3}\right)
Since \frac{35}{15} and \frac{3}{15} have the same denominator, add them by adding their numerators.
\frac{38}{15}-\frac{4}{15}=\frac{4}{5}x\left(\frac{3}{2}+\frac{4}{3}\right)
Add 35 and 3 to get 38.
\frac{38-4}{15}=\frac{4}{5}x\left(\frac{3}{2}+\frac{4}{3}\right)
Since \frac{38}{15} and \frac{4}{15} have the same denominator, subtract them by subtracting their numerators.
\frac{34}{15}=\frac{4}{5}x\left(\frac{3}{2}+\frac{4}{3}\right)
Subtract 4 from 38 to get 34.
\frac{34}{15}=\frac{4}{5}x\left(\frac{9}{6}+\frac{8}{6}\right)
Least common multiple of 2 and 3 is 6. Convert \frac{3}{2} and \frac{4}{3} to fractions with denominator 6.
\frac{34}{15}=\frac{4}{5}x\times \frac{9+8}{6}
Since \frac{9}{6} and \frac{8}{6} have the same denominator, add them by adding their numerators.
\frac{34}{15}=\frac{4}{5}x\times \frac{17}{6}
Add 9 and 8 to get 17.
\frac{34}{15}=\frac{4\times 17}{5\times 6}x
Multiply \frac{4}{5} times \frac{17}{6} by multiplying numerator times numerator and denominator times denominator.
\frac{34}{15}=\frac{68}{30}x
Do the multiplications in the fraction \frac{4\times 17}{5\times 6}.
\frac{34}{15}=\frac{34}{15}x
Reduce the fraction \frac{68}{30} to lowest terms by extracting and canceling out 2.
\frac{34}{15}x=\frac{34}{15}
Swap sides so that all variable terms are on the left hand side.
x=\frac{34}{15}\times \frac{15}{34}
Multiply both sides by \frac{15}{34}, the reciprocal of \frac{34}{15}.
x=1
Cancel out \frac{34}{15} and its reciprocal \frac{15}{34}.
