Question

5. Verify a - (- 6) = a + b for the following values of a
and b.
(a) a = 25, b = 3 (b) a = 50, b = 75
(c) a = 18, b = 26 (d) a = 100, b = 200​

Answer 1

Answer:

(a)25-(-6)=25+3

25+6=25+3

31 ≠ 28

therefore,

a-(-6)≠a+b

(b)50-(-6)=50+75

50+6=50+75

56≠125

therefore,

a-(-6)≠a+b

(c)18-(-6)=18+26

18+6=18+26

24≠44

therefore,

a-(-6)≠a+b

(d)100-(-6)=100+200

100+6=100+200

106≠300

therefore,

a-(-6)≠a+b
