Math Problem Statement
The steps to correctly solve an equation are shown. Move a property into each box of the Reason column to justify each step.
Solution
Let's solve this step-by-step and match the appropriate property with each equation transformation:
-
Step 1:
- Reason: This is the original equation (already provided).
-
Step 2:
- Reason: This transformation uses the distributive property (distributing to both and ).
-
Step 3:
- Reason: Here, the is subtracted from both sides, leaving . This applies the subtraction property of equality.
-
Step 4:
- Reason: Adding to both sides eliminates the , using the addition property of equality.
-
Step 5:
- Reason: Dividing both sides by gives , which uses the division property of equality.
Thus, the table would look like this:
Step | Equation | Reason |
---|---|---|
1 | original equation | |
2 | distributive property | |
3 | subtraction property of equality | |
4 | addition property of equality | |
5 | division property of equality |

Here are some related questions for you to explore:
- What is the associative property and when would you use it in solving equations?
- How does the commutative property differ from the distributive property?
- Why is it important to understand properties of equality in solving equations?
- Can you provide an example where the multiplication property of equality is used?
- What is the reflexive property of equality and how might it apply to algebra?
Tip: The distributive property allows you to multiply a number by a group of terms inside parentheses, a key step in simplifying algebraic expressions.
