Equivalent Inequalities - Definition & Examples

Suppose you solve the inequality above by the following steps:

1. Subtract the red constant from both sides.
2. Subtract the orange constant from both sides.
3. Divide both sides by the blue coefficient.

At the end, you get a solution of the form $x\leq \star$, where $\star$ is some constant. Which of the colors represents the reason for flipping the inequality sign?
