Question

If a=75 and b= 84 then verify a-(-b) = a+b.

Answer 1

Answer:

a – (-b) = 21-(-18)

21-(-18) = 21 + 18

21+18= 39

a + b = 21+18

21+18 = 39

Answer 2

Answer:

Ok FRIEND

Here you go

Putting values in place

75-(-84) = 75 + 84 ( because the sign changes since before the bracket is -,it will get multiplied with the - inside the bracket and change into + )

So, 75 + 84 = 159

and, in this way we verify that 75-(-84)= 75 + 84

HOPE IT HELPS
