Solve for y -5/y<0

$- \frac{5}{y} < 0$

Find all the values where the expression switches from negative to positive by setting each factor equal to $0$ and solving.

$y = 0$

The domain is all values of $y$ that make the expression defined.

$(- \infty, 0) \cup (0, \infty)$

The solution consists of all of the true intervals.

$y > 0$

The result can be shown in multiple forms.

Inequality Form:

$y > 0$

Interval Notation:

$(0, \infty)$
