Answer 1

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\huge{\boxed{\bullet{\color{cyan}{\mathbb{ANSWER}}}\bullet}}\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:$

a = (-8)

b = (-7)

1.) a - b

=> (-8) - (-7)

=> (-8) + 7

=> (-1)

2.) b - a

=> (-7) - (-8)

=> (-7) + 8

=> 1

Now,

➙ (-1) ≠ 1

=> a - b ≠ b - a

Hence proved

Answer 2

Step-by-step explanation:

a-b

= -8 - ( - 7)

= -8+7= -1

b-a

= -7 -(-8)

= -7+8

= 1

hence proved
