Which of the following equations can be formed using the expression x = 5:

Options

A. `2x+3=13`
B. `3x+2=13`
C. `x-5=1`
D. `4x-9=21`

Answer

To solve the question of which equations can be formed using the expression \( x = 5 \), we can evaluate each option step by step.

### Step-by-Step Solution:

1. **Identify the expression**: We know that \( x = 5 \).

2. **Evaluate Option A**:
- The equation is \( 2x + 3 \).
- Substitute \( x = 5 \):
\[ 2(5) + 3 = 10 + 3 = 13 \]
- This equation holds true.

3. **Evaluate Option B**:
- The equation is \( 3x + 2 \).
- Substitute \( x = 5 \):
\[ 3(5) + 2 = 15 + 2 = 17 \]
- This does not hold true since we are looking for 13.

4. **Evaluate Option C**:
- The equation is \( x - 5 \).
- Substitute \( x = 5 \):
\[ 5 - 5 = 0 \]
- This does not hold true since we are looking for 1.

5. **Evaluate Option D**:
- The equation is \( 4x - 9 \).
- Substitute \( x = 5 \):
\[ 4(5) - 9 = 20 - 9 = 11 \]
- This does not hold true since we are looking for 21.

### Conclusion:
The only equation that can be formed using the expression \( x = 5 \) is **Option A**: \( 2x + 3 = 13 \).
