9\left(12x-\frac{6x}{9}-\frac{x}{3}\right)-5x=0
Multiply both sides of the equation by 9, the least common multiple of 9,3.
9\left(12x-\frac{2}{3}x-\frac{x}{3}\right)-5x=0
Divide 6x by 9 to get \frac{2}{3}x.
9\left(\frac{35}{3}x-\frac{2}{3}x\right)-5x=0
Combine 12x and -\frac{x}{3} to get \frac{35}{3}x.
9\times \frac{35}{3}x+9\left(-\frac{2}{3}x\right)-5x=0
Use the distributive property to multiply 9 by \frac{35}{3}x-\frac{2}{3}x.
\frac{9\times 35}{3}x+9\left(-\frac{2}{3}x\right)-5x=0
Express 9\times \frac{35}{3} as a single fraction.
\frac{315}{3}x+9\left(-\frac{2}{3}x\right)-5x=0
Multiply 9 and 35 to get 315.
105x+9\left(-\frac{2}{3}x\right)-5x=0
Divide 315 by 3 to get 105.
100x+9\left(-\frac{2}{3}x\right)=0
Combine 105x and -5x to get 100x.
100x-9\times \frac{2}{3}x=0
Multiply 9 and -1 to get -9.
100x+\frac{-9\times 2}{3}x=0
Express -9\times \frac{2}{3} as a single fraction.
100x+\frac{-18}{3}x=0
Multiply -9 and 2 to get -18.
100x-6x=0
Divide -18 by 3 to get -6.
94x=0
Combine 100x and -6x to get 94x.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 94 is not equal to 0, x must be equal to 0.
