Question

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

Answer 1

Answer:

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

(-15) = (-9-6)

(-15)= (-15)

Answer 2

Given➞

a = -9

b = -6

To show➞

(a - b) = (b+a)

Solution➞

$LHS = a - b \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = - 9 - ( - 6)\\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = - 9 + 6 \\ \: \: \: \: \: \: \: = - 3\\ \\ RHS = b + a \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: = - 6 - 9 \\ \: \: \: \: \: \: \: \: \: = - 15$

LHS ≠ RHS

Hence, (a - b) ≠ (b+a).

It is not possible that, (a - b) = (b+a).
