    Ordinary D.E - integrating factor method

    Hi everyone

    Need help to verify this working, thank you in advance for all your kind help & support.

    \frac{dy}{dx} + 5y=e^{-2x}
    Integral factor
    e^{\int5dx}=e^{5x}

    Multiply by U.F & integrate
    e^{5x}.y=\int e^{5x}.e^{-2x}dx + c]
    ye^{5x}=\frac{1}{3}e^{3x}+c or
    y = \frac{1}{3}e^{-2x}+ce^{-5x}

    Thank you .
