If the inequality MX > 2, multiply both sides by 1m at the same time, we can get x < 2m, and find the value range of M

If the inequality MX > 2, multiply both sides by 1m at the same time, we can get x < 2m, and find the value range of M

Because MX > 2, there is x < 2m, according to the basic properties of inequality: 1m < 0, that is m < 0. So the answer is: m < 0
