Question

7. Verify:a-(- b) = a + b for a=25 and b= - 30.​

Answer 1

Step-by-step explanation:

a-(-b) = a+b

a= 25 and b= -30

So

Lhs. Rhs

25-[-(-30)]. 25+(-30)

25+(-30). -5

-5

-5=-5

LHS=RHS

Hence ,verified.

Hope it helps !!

Answer 2

Answer:

Step-by-step explanation:

a - ( - b ) = a + b

a = 25 , b = - 30

25 - ( - ( - 30)) = 25 + ( - 30)

25 - ( 30 ) = 25 - 30

25 - 30 = - 5

- 5 = - 5

hence , proved
