$y = \log_{3} (\frac{4 + 5 x}{3 - x})$

Step 1

Split the fraction $\frac{4 + 5 x}{3 - x}$ into two fractions.

$y = \log_{3} (\frac{4}{3 - x} + \frac{5 x}{3 - x})$

Step 2

Combine the numerators over the common denominator.

$y = \log_{3} (\frac{4 + 5 x}{3 - x})$

Step 3

The given equation $y = \log_{3} (\frac{4 + 5 x}{3 - x})$ can not be written as $y = k x$ , so $y$ doesn't vary directly with $x$ .

$y$ doesn't vary directly with $x$
