Differential equations — practice question

The variables $x$ and $y$ are linked by the differential equation $\frac{dy}{dx} = \frac{6xe^{3x}}{y^2}$. You are told that $y = 2$ when $x = 0$.
(main)[8]

Find the solution of the differential equation and hence determine the value of $y$ when $x = 0.5$, correct to 2 decimal places.
