Answer:


\boxed {\boxed {\sf x <7}}

Explanation:

To solve the inequality you must isolate the variable, which is x.


2x-5 < 9

5 is being subtracted from 2x. The inverse of subtraction is addition, so add 5 to both sides of the equation.


2x-5+5 < 9+5


2x < 14

x is being multiplied by 2. The inverse of multiplication is division, so divide both sides by 2.


\frac {2x}{2} < \frac {14}{2}


x <7

The solution to this inequality is x <7
