The task is to move 2 matches in the equation `3 + 3 = 8` to make it true. Let's solve this step by step.
Initial Equation:
```
3 + 3 = 8
```
Matches Representation:
- The number `3` is made using 5 matches.
- The `+` sign uses 2 matches.
- The `=` sign uses 2 matches.
- The number `8` is made using 7 matches.
Goal:
We need to move exactly 2 matches to make the equation true.
---
Step-by-Step Solution:
1.
Analyze the Current Equation:
- The current equation `3 + 3 = 8` is false because \(3 + 3 = 6\), not 8.
2.
Think Creatively About Match Movements:
- We can change the numbers or the operators by moving matches.
- The target is to form a valid equation that is true.
3.
Consider Possible Changes:
- Changing the `+` sign to another operator (e.g., `-`, `=`, etc.).
- Changing one or both of the `3`s into different numbers.
- Changing the `8` into a different number.
4.
Trial and Error with Match Movements:
- One effective approach is to change the `+` sign into a `-` sign and adjust the numbers accordingly.
5.
Solution Approach:
- Move 1 match from the `+` sign to turn it into a `-` sign.
- Move 1 match from the second `3` to change it into a `7`.
6.
New Equation After Moving Matches:
- Change the `+` sign to a `-` sign by removing one vertical match from the `+`.
- Change the second `3` into a `7` by adding the removed match to the top right of the `3`.
The new equation becomes:
```
3 - 3 = 0
```
7.
Verify the New Equation:
- The equation `3 - 3 = 0` is true because \(3 - 3 = 0\).
---
Final Answer:
Move 1 match from the `+` sign to turn it into a `-` sign, and move 1 match from the second `3` to turn it into a `7`. The resulting equation is:
```
3 - 3 = 0
```
Thus, the solution is:
\[
\boxed{3 - 3 = 0}
\]
