    I get

    \displaystyle y' x = 4y

    \displaystyle \frac{dy}{dx}x = 4y

    \displaystyle \frac{dy}{y}= \frac{4}{x}~dx

    \displaystyle \int \frac{dy}{y}= \int \frac{4}{x}~dx

    \displaystyle \ln y =  4\int \frac{1}{x}~dx

    \displaystyle \ln y =  4\ln x +C

     \displaystyle y =  e^{4\ln x +C}
