4x=9y\times 27,12
Multiply both sides of the equation by 36, the least common multiple of 9;4.
4x=244,08y
Multiply 9 and 27,12 to get 244,08.
4x=\frac{6102y}{25}
The equation is in standard form.
\frac{4x}{4}=\frac{6102y}{4\times 25}
Divide both sides by 4.
x=\frac{6102y}{4\times 25}
Dividing by 4 undoes the multiplication by 4.
x=\frac{3051y}{50}
Divide \frac{6102y}{25} by 4.
