Question

11. If a = -9 and b = -6, show that (a - b) = (b - a).​

Answer 1

a-b=-9+6=-3

b-a=-6+9=3

Answer 2

Step-by-step explanation:

Given a = -9 and b= -6

we have to prove that (a-b) = (b-a)

(a-b) = ( -9 -(-6)

= -9 +6

= -3

(b-a) = (-6 -(-9)

= -6 + 9

= 3

but (a-b) is not equal to (b-a)
