Calculate. $\frac{1}{x}﻿-4<0$

First add 4 to both sides.
We get:
1/x < 4
Then multiply both sides by x.
We get:
1<4x.
Now divide both sides by 4.
We get:
1/4 < x.
Therefore, x>1/4.

I'll assume you want to solve for x
$\frac{1}{x}-4<0←$ add 4 to bothsides
$\frac{1}{x}-4+4<0+4$
$\frac{1}{x}<4$ now solve for x, multiply both sides by x first
$x\ast \frac{1}{x}<4\ast x$
$1<4x←$ divide both sides by 4
$1\ast \frac{1}{4}<4x\ast \frac{1}{x}$
$\frac{1}{4} (answer)
