Question

Verify a-(-b) =a + b for the following values of ‘a’ and ‘b’
a. a=34 b=73
b. a=45 b=30

Answer 1

Answer:

Step-by-step explanation:

FIRST CASE :

a = 34

b = 73

a-(-b) = a + b

34 - (-73) = 34 + 73

as we know that, minus * minus = plus

34 + 73 = 34 + 73

107 = 107

LHS = RHS

second case :

a = 45

b = 30

a-(-b) = a + b

45 - (-30) = 45 + 30

as we know that, minus * minus = plus

45 + 30 = 45 + 30

75 = 75

LHS = RHS

Answer 2

Answer:

Step-by-step explanation:

a=34 b=73

a-(-b) =a + b

34-(-73)= 34+73

34+73=107

107=107

LHS=RHS

Hence proved

a = 45

b = 30

a-(-b) = a + b

45 - (-30) = 45 + 30

as we know that, minus * minus = plus

45 + 30 = 45 + 30

75 = 75

LHS = RHS
