If the solution set of inequality ax > b about X is (1, positive infinity), then the solution set of inequality (ax-b) / X-2 > 0 about X is (1, positive infinity) The answer is less than negative 1, greater than 2. Why is a greater than zero? If B is negative, it's OK

If a * x > b, the corresponding solution set is (1, positive infinity), that is, x > 1
