Question

verify: a-(-b)= a+ b for the following values of a and b
a. a=25, b=12
b. a=113, b=16​

Answer 1

Answer:-

a) a = 25, b = 12

LHS = a - ( -b )

= 25 - ( -12 )

= 25 + 12

= 37

RHS = a + b

= 25 + 12

= 37

LHS = RHS

b) a = 113, b = 16

LHS = a - ( -b )

= 113 - ( - 16 )

= 113 + 16

= 129

RHS = a + b

= 113 + 16

= 129

LHS = RHS

( Hence Proved )

Answer 2

Step-by-step explanation:

putting

a=25, b=12

a-(-b)= a+ b

25 -(-12) = 25 +12

25 +12 = 12 +25 ---- (-×- = +)

37 = 37

hence verify

2nd

a=113, b=16

113 -(-16) = 113 +16 ---- (-×- = +)

113 +16 = 113 + 16

129 = 129

hence verify
