Solve the differential equation dy/dx+4xy=x
Irina-Kira [14]
\dfrac{\mathrm dy}{\mathrm dx}+4xy=x
\dfrac{\mathrm dy}{\mathrm dx}=x(1-4y)

This ODE is separable, so you can write

\dfrac{\mathrm dy}{1-4y}=x\,\mathrm dx

Integrating both sides gives

-\dfrac14\ln|1-4y|=\dfrac12x^2+C
\ln|1-4y|=-2x^2+C
1-4y=e^{-2x^2+C}
1-4y=Ce^{-2x^2}
y=\dfrac{1-Ce^{-2x^2}}4
