I need to know how to slove this math problem..

1/y-4

Is this supposed to be an equation?

$\frac 1y -4= 0\,??$

if so, add 4 to both sides

$\frac 1y = 4$

multiply both sides by y and divide both sides by 4

$\frac 14 = y$

Or perhaps

$\frac{1}{y-4} = 0$

Then,

$y-4=0$

and

$y=4$

EDIT : this is to find the asymptote of the graph

Oh, silly me... y=4 refers to the asymptote of the graph
