If x < y, then all of the following are true except

x/2 < x/2
- x < - y
x + 2 < y + 2
2 x < 2 y

These expressions are not true.

Step-by-step explanation:

The first option is not true, because is , it implies that . Also, there doesn't exist a number that is reflexive regarding < or > relations, because a number is not more or less than itself, the reflexive property is applied with equalities, or relations, because the equality signs is included.

The other expression that is not true is the second one, because when we multiply or divide a negative number in a inequality, the relations changes, for example:

As you can see, the relations changed from < to >, demonstrating that is not true.

Therefore the first and second options are false.
