Question

Verify a – (– b) = a + b for the following values of a and b. A) a=75,84=

Answer 1

Question:

To verify a-(-b) = a+b, for a = 75 and b = 84

Solution:

Given,

a = 75

b = 84

To prove,

a-(-b) = a+b for the above values of a and b.

a-(-b) ---> LHS

75-(-84)

75+84

159 ---> This is the value of LHS

a+b ---> RHS

75+84

159 ---> This is the value of RHS

159 = 159

75-(-84) = 75+84

a-(-b) = a+b

LHS = RHS

Hence Verified!
