The equation that would have the solution of n=22 is n + 15 = 7 + 15.
NO
Apologies for the mistake. Let's go through each equation to find the correct one.
1) 3n - 28 = 38 - 14
For n=22:
3(22) - 28 = 38 - 14
66 - 28 = 24
38 = 24 (which is not true)
2) n + 15 = 7 + 15
For n=22:
22 + 15 = 7 + 15
37 = 22 (which is not true)
3) n + 16 = 38 - 15
For n=22:
22 + 16 = 38 - 15
38 = 38 (which is true)
4) n + 16 = 18 + 20
For n=22:
22 + 16 = 18 + 20
38 = 38 (which is true)
Therefore, the equations with the solutions of n=22 are n + 16 = 38 - 15 and n + 16 = 18 + 20.

38 = 38 (which is true)
4) n + 16 = 18 + 20
For n=22:
22 + 16 = 18 + 20
38 = 38 (which is true)
Therefore, the equations with the solutions of n=22 are n + 16 = 38 - 15 and n + 16 = 18 + 20.
