Question

If  a = 3 and b = -5 and a + b = b + a. Then , what is the value of c in this equation
(a + b) - (b + a) + a + (-b) = c
  1. 8


Solution

The correct option is A 8
As we know that the commutative property of integers under addition states that
a + b = b + a, such that a and b are integers.
 (a + b) - (b + a) + a + (-b) = c
a + (-b) = c
3 + ( 5) = 8 [ Using the values of a and b from the given values]
