Answer 1

Answer:

in (a+b)

we put the values

= -9+(-6)= -15

in (b+a)

-6 + (-9) = -15

it shows that a+b is equal to b+a coz there answrrs are same

Answer 2

Step-by-step explanation:

Consider eqn a+b

Given a=-9,b=-6

-9+-6=-15

b+a=-6+-9=-15

Addition is commutative in nature

Therefore a+b=b+a
