Question

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

Answer 1

Correct question:

If a = -9 and b = -6, show that (a - b) is not equal to (b-a).

Answer:

Given:

a = -9 and b = -6

To Show:

We need to show that (a - b) is not equal to (b-a).

Solution:

Taking LHS,

=> (a - b)

= {-9 - (-6)}

= (-9 + 6)

= (-3)

Taking RHS,

=> (b - a)

= {-6 -(-9)}

= (-6 + 9)

= (+3)

Clearly, -3 is not equal to 3.

LHS is not equal to RHS.

Therefore (a - b) is not equal to (b - a).

Hence proved!

Answer 2

Answer:

a = -9

b = -6

so , we have to show (a - b) + (b - a)

= (a - b)

= ((-9) - (-6))

= (-9+6)

= -3

= (b - a)

= ((-6) - (-9))

= ((-6) + 9)

= +3

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

= a - b =

= -3

= b - a =

= +3

= (-3) + 3

= 0

the answer is 0
