Final answer:

The equation 32-4x=12 is the only one that has the solution x = 5 because when you substitute 5 for x in this equation, it equals 12, making it a true statement.

Step-by-step explanation:

To determine which equations have the solution x = 5, we need to substitute x with 5 in each equation and see if it results in a true statement.

  1. 25x+4=9: 25(5)+4=125+4=129 ≠ 9 → Incorrect
  2. 18−2x=9: 18−2(5)=18−10=8 ≠ 9 → Incorrect
  3. x5+5=6: 5(5)+5=25+5=30 ≠ 6 → Incorrect
  4. 11 + 6x = 22: 11 + 6(5)= 11 + 30 = 41 ≠ 22 → Incorrect
  5. 32−4x=12: 32−4(5)=32∔20=12 → Correct
  6. 3x + 1 = 9: 3(5) + 1 = 15 + 1 = 16 ≠ 9 → Incorrect

Only the equation 32−4x=12 has the solution x = 5 because when substituting 5 for x, it results in a true statement.

It would be 32-4x=12
32-4(5)=12
32-20=12
12=12
