Question

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

Answer 1

Answer:a-b

(-10)-(-4)

= -10+4

= -6

b-a

(-4)-(-10)

= -4+10

= 6

Since,

a-b = -6

b-a = 6

they are not equal

hence proved

Answer 2

Answer:

a=-9

b=-6

Step-by-step explanation:

(a-b)+(b-a)=

(-9(-)-6)+(-6(-)-6)

=-15+(-12)

=-27
