Your question seems to indicate some confusion as to the meaning of "clearing fractions"
The clearing of fractions simply means that, after you have multiplied by the number (usually this will be the LCD of the all the fractions in the equation or expression), then you will have only integers as coefficients or contants left in the equation. In your equation:
Multiply both sides by the LCD of the two fractions, this will be 9.

Since the denominators are "3" and "9" the
least common denominator (LCD) is "9".
You multiply both sides of the equation by
9 to get rid of the denominators.
