\frac{4x}{9}+\frac{5x}{24}+\frac{20x}{81}+60=x
Anything divided by one gives itself.
\frac{8\times 4x}{72}+\frac{3\times 5x}{72}+\frac{20x}{81}+60=x
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 9 and 24 is 72. Multiply \frac{4x}{9} times \frac{8}{8}. Multiply \frac{5x}{24} times \frac{3}{3}.
\frac{8\times 4x+3\times 5x}{72}+\frac{20x}{81}+60=x
Since \frac{8\times 4x}{72} and \frac{3\times 5x}{72} have the same denominator, add them by adding their numerators.
\frac{32x+15x}{72}+\frac{20x}{81}+60=x
Do the multiplications in 8\times 4x+3\times 5x.
\frac{47x}{72}+\frac{20x}{81}+60=x
Combine like terms in 32x+15x.
\frac{9\times 47x}{648}+\frac{8\times 20x}{648}+60=x
To add or subtract expressions, expand them to make their denominators the same. Least common multiple of 72 and 81 is 648. Multiply \frac{47x}{72} times \frac{9}{9}. Multiply \frac{20x}{81} times \frac{8}{8}.
\frac{9\times 47x+8\times 20x}{648}+60=x
Since \frac{9\times 47x}{648} and \frac{8\times 20x}{648} have the same denominator, add them by adding their numerators.
\frac{423x+160x}{648}+60=x
Do the multiplications in 9\times 47x+8\times 20x.
\frac{583x}{648}+60=x
Combine like terms in 423x+160x.
\frac{583x}{648}+60-x=0
Subtract x from both sides.
\frac{583x}{648}-x=-60
Subtract 60 from both sides. Anything subtracted from zero gives its negation.
583x-648x=-38880
Multiply both sides of the equation by 648.
-65x=-38880
Combine 583x and -648x to get -65x.
x=\frac{-38880}{-65}
Divide both sides by -65.
x=\frac{7776}{13}
Reduce the fraction \frac{-38880}{-65} to lowest terms by extracting and canceling out -5.
