Answer 2

Let's solve each equation step by step:

1. -0.5 + (-4.2 + 3.9):

   First, simplify the expression within the parentheses:

   -4.2 + 3.9 = -0.3

   Now, add -0.5 to -0.3:

   -0.5 + (-0.3) = -0.8

   So, the result is -0.8.

2. (X - 2) - (X + 3):

   Distribute the negative sign on the second set of parentheses:

   X - 2 - X - 3

   Now, combine like terms:

   (X - X) + (-2 - 3) = 0 - 5 = -5

   So, the result is -5.

3. P - (P - a):

   Distribute the negative sign on the second set of parentheses:

   P - P + a

   P and -P cancel each other out:

   0 + a = a

   So, the result is 'a' (assuming 'a' is a constant).

So, the results of the three equations are:

1. -0.5 + (-4.2 + 3.9) = -0.8
2. (X - 2) - (X + 3) = -5
3. P - (P - a) = a
