2. Solving Inequalities Using Addition or Subtraction
Sign In
The numbers that are shaded on the graph are the solution set of the inequality.
x ≤ 16, see solution.
Consider the given graph.
This inequality graph shows values less than or equal to 16. We can write this as an inequality if we let x represent any number in the solution set. x ≤ 16 Now let's describe a real-life situation. A group of 20 children is going to the movies. The oldest child is 16 years old. This inequality can represent the ages of all the children in the group. However, this is just one possible situation this inequality can describe.
