When dividing one side of an inequality with a positive number it's important to divide the other side by the same number to ensure that the inequality still holds. For example, the inequality $3x>12$ can be divided by $3$ on both sides. $\dfrac{3x}{{\color{#FF0000}{3}}} > \dfrac{12}{{\color{#FF0000}{3}}} \quad \Leftrightarrow \quad x>4.$ However, this only yields when dividing by positive numbers. When dividing both sides by a negative number the inequality sign must be flipped.
