Question

x is at most 6 and greater or equal to than 3.1

Answer 1

This question is incomplete. Is there anything else to go with this?

Answer 2

As the question stands, we have two inequalities:

x <= 6

or

x >= 3.1

Any value of x will satisfy one of these two inequalities.

If x = 7, x >=3.1 is true.
If x = 0, x <= 6 is true.
if x = 6, 6 <= 6 and x >=1 is true.
