Question

4) Check whether a + b = a - (-b) for
a = (-9) and b = 3

Answer 1

Step-by-step explanation:

lhs

a+b=-9+3=-6

rhs =-9-3=-12 so

lhs is not equals to rhs OK friend

Answer 2

Step-by-step explanation:

We have the Following equation;

a + b = a - (- b)     value a = (-9).

                            value b = (3).

we all at a certain standard have learnt about the +- law, in which it was stated that - and - = +.

We are inputing the value (-9) and (3).

(-9) + 3 = (-9) - (-3)

-9 + 3 = -9 + 3  ( - and - = +)

6 = 6 ( L.H.S = R.H.S).

So we have checked out that a + b = a - (-b).
