(dy)/(dx)+(-x)/(x+1)=0

\frac{d y}{d x} + \frac{- x}{x + 1} = 0

y = x + 1 - ln (x + 1) + c_{1}

Solution steps

\frac{d y}{d x} + \frac{- x}{x + 1} = 0

Substitute

\frac{d y}{d x}

with

y^{'} (x)

y^{^{'}} (x) + \frac{- x}{x + 1} = 0

Isolate

y^{'} (x) : y^{'} (x) = \frac{x}{x + 1}

f^{^{'}} (x) = g (x)

then

f (x) = \int g (x) d x

y = \int \frac{x}{x + 1} d x

\int \frac{x}{x + 1} d x = x + 1 - ln (x + 1) + c_{1}

y = x + 1 - ln (x + 1) + c_{1}
