Question

Verify a-(- b) = a + b for the following values of a and b.
(i) a = 21. b = 18
​

Answer 1

Answer:

a-(- b) = a + b

21-(-18) = 21+18

21+18=21+18

39 = 39

Answer 2

Answer:

Hey There!

____________

From the question,

a = 21 and b = 18

To verify a – (- b) = a + b

Let us take Left Hand Side (LHS) = a – (- b)

= 21 – (- 18)

= 21 + 18

= 39

Now, Right Hand Side (RHS) = a + b

= 21 + 18

= 39

By comparing LHS and RHS

LHS = RHS

39 = 39

Hence, the value of a and b is verified.
