Question

Which equation has a solution of x = 13?
x + 3 = 10
x minus 10 = 3
StartFraction x Over 2 EndFraction = 26
x + 12 = 1

Answer 1

To find which equation has the solution \( x = 13 \), we can substitute \( x = 13 \) into each equation and see if it holds true.

1. **For the equation \( x + 3 = 10 \)**:
\[
13 + 3 = 16 \quad (\text{not true})
\]

2. **For the equation \( x - 10 = 3 \)**:
\[
13 - 10 = 3 \quad (\text{true})
\]

3. **For the equation \( \frac{x}{2} = 26 \)**:
\[
\frac{13}{2} = 6.5 \quad (\text{not true})
\]

4. **For the equation \( x + 12 = 1 \)**:
\[
13 + 12 = 25 \quad (\text{not true})
\]

The only equation that holds true when substituting \( x = 13 \) is \( x - 10 = 3 \). Therefore, the answer is:

**x - 10 = 3**.
