\frac{d}{d x} (7 - 2 x)

- \frac{1}{7 - 2 x}

Solution steps

\frac{d}{d x} (7 - 2 x)

Apply the chain rule:

\frac{1}{2 7 - 2 x} \frac{d}{d x} (7 - 2 x)

= \frac{1}{2 7 - 2 x} \frac{d}{d x} (7 - 2 x)

\frac{d}{d x} (7 - 2 x) = - 2

= \frac{1}{2 7 - 2 x} (- 2)

Simplify

\frac{1}{2 7 - 2 x} (- 2) : - \frac{1}{7 - 2 x}

= - \frac{1}{7 - 2 x}
