2x=9\times 4,8
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 9x, the least common multiple of 9;x.
2x=43,2
Multiply 9 and 4,8 to get 43,2.
x=\frac{43,2}{2}
Divide both sides by 2.
x=\frac{432}{20}
Expand \frac{43,2}{2} by multiplying both numerator and the denominator by 10.
x=\frac{108}{5}
Reduce the fraction \frac{432}{20} to lowest terms by extracting and canceling out 4.
