Final answer:

Equations a, c, and d result in X = 6 when solved, whereas equation b results in X = 9. Therefore, equation b does not belong with the other three because it has a different solution for X.

Step-by-step explanation:

The question asks which equation does not belong with the other three, considering the options a) X – 2 = 4, b) X - 3 = 6, c) X - 5 = 1, and d) X - 6 = 0. To determine which one is different, we should solve each equation for X.

  • a) X = 4 + 2 = 6
  • b) X = 6 + 3 = 9
  • c) X = 1 + 5 = 6
  • d) X = 0 + 6 = 6

Equations a, c, and d all have the solution X = 6, while equation b has a different solution, X = 9. Therefore, equation b does not belong with the other three because it results in a different value for X when solved.
