Math Problem Statement
Solution
Let's solve the given inequality step by step.
The inequality is:
Step 1: Expand the expression on the right-hand side.
Distribute the over the terms inside the parentheses:
So, the inequality becomes:
Step 2: Combine like terms.
Now, combine the terms involving :
This simplifies the inequality to:
Step 3: Solve for .
First, subtract 15 from both sides:
Next, divide both sides by 7:
or equivalently:
Step 4: Graph the inequality.
The solution is , which means all values of less than or equal to 1. On a number line, this would be represented by a closed circle at with an arrow extending to the left (since is less than or equal to 1).
Final Answer:
- The correct answer for the inequality is .
- The graph should show a closed circle at and a line extending to the left, covering values less than or equal to 1.

- How do you solve inequalities with multiple steps?
- What happens if you multiply or divide an inequality by a negative number?
- How would the solution change if the inequality symbol was reversed?
- How can you check if a given value is a solution to an inequality?
- What is the difference between solving an equation and solving an inequality?
Tip: When graphing inequalities, always pay attention to whether the inequality is strict (< or >) or inclusive (≤ or ≥) for determining open or closed circles on the graph.
