2х-1<0

To solve the inequality 2x - 1 < 0, you need to isolate x on one side of the inequality symbol.

First, add 1 to both sides of the inequality:

2x - 1 + 1 < 0 + 1

This simplifies to:

2x < 1

Next, divide both sides of the inequality by 2:

(2x)/2 < 1/2

This simplifies to:

x < 1/2

Therefore, the solution to the inequality 2x - 1 < 0 is x < 1/2.
