integral of ((x+6))/((x+7))

\int \frac{( x + 6 )}{( x + 7 )} d x

- ln ∣ x + 7 ∣ + x + C

Solution steps

\int \frac{x + 6}{x + 7} d x

\frac{x + 6}{x + 7} = - \frac{1}{x + 7} + 1

= \int - \frac{1}{x + 7} + 1 d x

Apply the Sum Rule:

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

= - \int \frac{1}{x + 7} d x + \int 1 d x

\int \frac{1}{x + 7} d x = ln ∣ x + 7 ∣

\int 1 d x = x

= - ln ∣ x + 7 ∣ + x

Add a constant to the solution

= - ln ∣ x + 7 ∣ + x + C
