Evaluate g(r)=25-3r

$g (r) = 25 - 3 r$

Divide each term in $g r = 25 - 3 r$ by $r$ .

$\frac{g r}{r} = \frac{25}{r} + \frac{- 3 r}{r}$

Simplify the left side.

Cancel the common factor of $r$ .

Cancel the common factor.

$\frac{g r}{r} = \frac{25}{r} + \frac{- 3 r}{r}$

Divide $g$ by $1$ .

$g = \frac{25}{r} + \frac{- 3 r}{r}$

$g = \frac{25}{r} + \frac{- 3 r}{r}$

$g = \frac{25}{r} + \frac{- 3 r}{r}$

Simplify the right side.

Cancel the common factor of $r$ .

Cancel the common factor.

$g = \frac{25}{r} + \frac{- 3 r}{r}$

Divide $- 3$ by $1$ .

$g = \frac{25}{r} - 3$

$g = \frac{25}{r} - 3$

$g = \frac{25}{r} - 3$
