(1) a= 21, b = 18
(ü) a= 118, b = 125
(ii) a= 75, b = 84
(iv) a= 28, b= 11​

Answer 1

Answer:

Step-by-step explanation:

Correct Question :-

Verify a-(-b) = a + b for the following values of a and b

1) a = 21, b = 18

2) a = 118 , b = 125

3) a = 75 , b = 84

4) a = 28 , b = 11

Solution :-

1) a = 21, b = 18

a-(-b) = a + b

Taking L.H.S :-

21 - ( - 18)

=  21 + 18

= 39

Taking R.H.S :-

21 + 18

= 39

Hence, L.H.S = R.H.S

2)  a = 118 , b = 125

Taking L.H.S :-

118-(-125)

= 118 + 125

= 243

Taking R.H.S :-

118 + 125

= 243

Hence, L.H.S = R.H.S

3) a = 75 , b = 84

Taking L.H.S :-

75 - ( - 84)

= 75 + 84

= 159

Taking R.H.S :-

75 + 84

= 159

Hence, L.H.S = R.H.S.

4) a= 28, b= 11​

Taking L.H.S :-

28 - (-11)

= 28 + 11

= 39

Taking R.H.S :-

28 + 11

= 39

Hence, L.H.S = R.H.S
