Question

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

Answer 1

༻ Solution ༺

a = 25 ------ ( Given )

b = 12 ------- ( Given )

⇝ Substitute these values in the equation :-

↝a - ( - b ) = a + b

↝25 - ( - 12 ) = 25 + 12

↝25 + 12 = 25 + 12 ------ [ ( - ) × ( - ) = ( + ) ]

↝ 37 = 37

↝LHS = RHS

Answer 2

a-(-b) = a + b

25 - (-12) = 25 + 12

25 + 12 = 25 = 12 (negative × negative = positive)

37 = 37

LHS = RHS. (verified)
