2х-1<0

To solve the inequality 2x - 1 < 0, we need to isolate the variable x.

Let's begin by moving the constant term -1 to the other side of the inequality by adding 1 to both sides:

2x - 1 + 1 < 0 + 1 2x < 1

Now, divide both sides of the inequality by 2 to solve for x:

2x/2 < 1/2 x < 1/2

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