Let's solve each equation one by one:

1. Equation: $x + 5 = 7$

   • Subtract 5 from both sides: $x = 7 - 5 = 2$
   • None of the options provided match $x = 2$.

2. Equation: $x - 5 = 9$

   • Add 5 to both sides: $x = 9 + 5 = 14$
   • None of the options provided match $x = 14$.

3. Equation: $23x + 43 = 3$

   • Subtract 43 from both sides: $23x = 3 - 43 = -40$
   • Divide both sides by 23: $x = \frac{-40}{23} \approx -1.74$
   • None of the options provided match this result.

4. Equation: $3x - 13 = 5$

   • Add 13 to both sides: $3x = 5 + 13 = 18$
   • Divide both sides by 3: $x = \frac{18}{3} = 6$
   • None of the options provided match $x = 6$.

5. Equation: $x + 1 = 6$

   • Subtract 1 from both sides: $x = 6 - 1 = 5$
   • None of the options provided match $x = 5$.

6. Equation: $x + 23 = 4$

   • Subtract 23 from both sides: $x = 4 - 23 = -19$
   • None of the options provided match $x = -19$.

7. Equation: $x - 7 = 8$

   • Add 7 to both sides: $x = 8 + 7 = 15$
   • None of the options provided match $x = 15$.

8. Equation: $x + 9 = 4$

   • Subtract 9 from both sides: $x = 4 - 9 = -5$
   • None of the options provided match $x = -5$.

9. Equation: $x + 1 = 8$

   • Subtract 1 from both sides: $x = 8 - 1 = 7$
   • None of the options provided match $x = 7$.

10. Equation: $x + 33 = 2$

    • Subtract 33 from both sides: $x = 2 - 33 = -31$
    • None of the options provided match $x = -31$.

None of the provided options for any of the equations match the correct solutions.
