Math Problem Statement
Solution
To determine which inequalities can be solved using only the Addition Property of Inequality, let’s examine each option and identify whether adding or subtracting a term will isolate the variable without needing any other operations, such as multiplication or division.
Analysis of Each Option:
-
Option A:
- To isolate , we can add to both sides:
- This inequality can indeed be solved using only addition.
-
Option B:
- To isolate , we would need to divide both sides by , which is not allowed using only the Addition Property of Inequality.
- This inequality cannot be solved using only addition.
-
Option C:
- To isolate , we would need to multiply both sides by , not allowed by the Addition Property of Inequality.
- This inequality cannot be solved using only addition.
-
Option D:
- To isolate , we can add to both sides:
- This inequality can indeed be solved using only addition.
-
Option E:
- To isolate , we can add to both sides:
- This inequality can be solved using only addition.
Conclusion:
The inequalities that can be solved using only the Addition Property of Inequality are:
- A:
- D:
- E:

Here are five additional questions that build on this topic:
- How does the Addition Property of Inequality differ from the Multiplication Property of Inequality?
- Can subtraction also be considered part of the Addition Property of Inequality?
- Why can’t inequalities involving division be solved with the Addition Property alone?
- How would the solution change if the inequality had a negative coefficient on the variable?
- In what cases would you use the Multiplication Property of Inequality instead?
Tip: Remember, the Addition Property of Inequality states that you can add (or subtract) the same value from both sides of an inequality without changing its direction.
