Answer 1

Answer:

The answer to your question is  Equations 1, 2 and 5 are equivalent

Step-by-step explanation:

1.- Equation 1

    2 + x = 5              x = 5 - 2         x = 3

2.- Equation 2

    x + 1 = 4               x = 4 - 1         x = 3

3.- Equation 3

    9 + x = 6             x = 6 - 9         x = -3

4.- Equation 4

   x + (-4) = 7           x - 4 = 7          x = 7 + 4             x = 11

5.- Equation 5

   -5 + x = -2            x = 5 - 2         x = 3
