WebA compound inequality includes two inequalities in one statement. A statement such as 4 < x≤ 6 4 < x ≤ 6 means 4 < x 4 < x and x ≤6 x ≤ 6. There are two ways to solve compound inequalities: separating them into two separate inequalities or leaving the compound inequality intact and performing operations on all three parts at the same time. Web3. Solving some simple inequalities Suppose we want to solve the inequality x+3 > 2. We can solve this by subtracting 3 from both sides: x+3 > 2 x > −1 So the solution is x > −1. This means that any value of x greater than −1 satisﬁes x+3 > 2. Inequalities can be represented on a number line such as that shown in Figure 1. The solid line
