2 X -1>0

Interpretation: X^{-1} > 0 (i.e., 1/x > 0).

• Domain: x ≠ 0
• 1/x > 0 means x and the numerator (which is positive) have the same sign, so x must be positive.
• Check: if x = 1, 1/1 = 1 > 0; if x = -1, 1/(-1) = -1 < 0.

Solution: x > 0

Note: If the intended inequality was 2x - 1 > 0, then the solution would be x > 1/2.
