Answer: To determine which equation has the solution x = 5, we can substitute 5 into each equation and see which one results in a true statement.

Let's evaluate each equation:

1. 25/x + 4 = 9

Substituting x = 5:

25/5 + 4 = 9

5 + 4 = 9

9 = 9 (True)

2. x/5 + 5 = 6

Substituting x = 5:

5/5 + 5 = 6

1 + 5 = 6

6 = 6 (True)

3. 3x + 1 = 9

Substituting x = 5:

3(5) + 1 = 9

15 + 1 = 9

16 = 9 (False)

4. 18 - 2x = 9

Substituting x = 5:

18 - 2(5) = 9

18 - 10 = 9

8 = 9 (False)

5. 32 - 4x = 12

Substituting x = 5:

32 - 4(5) = 12

32 - 20 = 12

12 = 12 (True)

6. 11 + 6x = 22

Substituting x = 5:

11 + 6(5) = 22

11 + 30 = 22

41 = 22 (False)

From the evaluations, equations 1, 2, and 5 have the solution x = 5.
