\sqrt{\frac{4}{3}+\frac{1}{9}-\frac{1}{12}}=3x\left(\frac{1}{3}+\frac{1}{2}\right)
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
\sqrt{\frac{12}{9}+\frac{1}{9}-\frac{1}{12}}=3x\left(\frac{1}{3}+\frac{1}{2}\right)
Least common multiple of 3 and 9 is 9. Convert \frac{4}{3} and \frac{1}{9} to fractions with denominator 9.
\sqrt{\frac{12+1}{9}-\frac{1}{12}}=3x\left(\frac{1}{3}+\frac{1}{2}\right)
Since \frac{12}{9} and \frac{1}{9} have the same denominator, add them by adding their numerators.
\sqrt{\frac{13}{9}-\frac{1}{12}}=3x\left(\frac{1}{3}+\frac{1}{2}\right)
Add 12 and 1 to get 13.
\sqrt{\frac{52}{36}-\frac{3}{36}}=3x\left(\frac{1}{3}+\frac{1}{2}\right)
Least common multiple of 9 and 12 is 36. Convert \frac{13}{9} and \frac{1}{12} to fractions with denominator 36.
\sqrt{\frac{52-3}{36}}=3x\left(\frac{1}{3}+\frac{1}{2}\right)
Since \frac{52}{36} and \frac{3}{36} have the same denominator, subtract them by subtracting their numerators.
\sqrt{\frac{49}{36}}=3x\left(\frac{1}{3}+\frac{1}{2}\right)
Subtract 3 from 52 to get 49.
\frac{7}{6}=3x\left(\frac{1}{3}+\frac{1}{2}\right)
Rewrite the square root of the division \frac{49}{36} as the division of square roots \frac{\sqrt{49}}{\sqrt{36}}. Take the square root of both numerator and denominator.
\frac{7}{6}=3x\left(\frac{2}{6}+\frac{3}{6}\right)
Least common multiple of 3 and 2 is 6. Convert \frac{1}{3} and \frac{1}{2} to fractions with denominator 6.
\frac{7}{6}=3x\times \frac{2+3}{6}
Since \frac{2}{6} and \frac{3}{6} have the same denominator, add them by adding their numerators.
\frac{7}{6}=3x\times \frac{5}{6}
Add 2 and 3 to get 5.
\frac{7}{6}=\frac{3\times 5}{6}x
Express 3\times \frac{5}{6} as a single fraction.
\frac{7}{6}=\frac{15}{6}x
Multiply 3 and 5 to get 15.
\frac{7}{6}=\frac{5}{2}x
Reduce the fraction \frac{15}{6} to lowest terms by extracting and canceling out 3.
\frac{5}{2}x=\frac{7}{6}
Swap sides so that all variable terms are on the left hand side.
x=\frac{7}{6}\times \frac{2}{5}
Multiply both sides by \frac{2}{5}, the reciprocal of \frac{5}{2}.
x=\frac{7\times 2}{6\times 5}
Multiply \frac{7}{6} times \frac{2}{5} by multiplying numerator times numerator and denominator times denominator.
x=\frac{14}{30}
Do the multiplications in the fraction \frac{7\times 2}{6\times 5}.
x=\frac{7}{15}
Reduce the fraction \frac{14}{30} to lowest terms by extracting and canceling out 2.
