Question

verify a-(-b)=a+b. a=(-28).b=11.​

Answer 1

Step-by-step explanation:

LHS

a-(-b)

-28-(-11)

-28+11

-17

RHS

-28+11

-17

LHS=RHS

a-(-b)= a+b

hence proved........

Answer 2

Answer:

a = ( - 28 )

b = 11

a - ( - b ) = a + b

(- 28) - (-11) = - 28 + 11

- 28 + 11 = - 28 + 11

- 17 = - 17

Hence verify , L.H.S = R.H.S
