olve the following:
Verify x-(-y) = x +y for the for the following values of a and b
(i)x= 21, y = 18
(ii) x= 118, y = 125
(iii) x = 75, y = 84
(iv) x = 28, y = 11
​

Answer 1

Answer:

1. 21+18=39

2.118+125=243

3.75+84=159

4.28+11=39

because x-(-y)=x+y

Answer 2

Answer:

i x-(-y)=x+y

x=21 ;y =18

arrange the values

21-(-18)=21+18

21+18=21+18

39=39

therefore,LHS=RHS
