Step-by-step Solution

Specify the solving method

1

Group the terms of the differential equation. Move the terms of the $y$ variable to the left side, and the terms of the $x$ variable to the right side of the equality

$\frac{1}{y\left(1-y\right)}dy=dx$
2

Integrate both sides of the differential equation, the left side with respect to $y$, and the right side with respect to $x$

$\int\frac{1}{y\left(1-y\right)}dy=\int1dx$
3

Solve the integral $\int\frac{1}{y\left(1-y\right)}dy$ and replace the result in the differential equation

$\ln\left(y\right)-\ln\left(-y+1\right)=\int1dx$
4

Solve the integral $\int1dx$ and replace the result in the differential equation

$\ln\left(y\right)-\ln\left(-y+1\right)=x+C_0$
5

Find the explicit solution to the differential equation. We need to isolate the variable $y$

$y=\frac{e^x}{C_1+e^x}$

Final Answer

$y=\frac{e^x}{C_1+e^x}$
