Answer:
Step-by-step explanation:
(i) a = 21, b = 18
Solution:-
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.
(ii) a = 118, b = 125
Solution:-
From the question,
a = 118 and b = 125
To verify a – (- b) = a + b
Let us take Left Hand Side (LHS) = a – (- b)
= 118 – (- 125)
= 118 + 125
= 243
Now, Right Hand Side (RHS) = a + b
= 118 + 125
= 243
By comparing LHS and RHS
LHS = RHS
243 = 243
Hence, the value of a and b is verified.
