Question

If a = (-11) and b = (18), test if a - b = b - a. Please help me with my homework.

Answer 1

Taking LHS

(-11)- (18)

→ -11-18

→ -29

Taking RHS

(18)-(-11)

→18+11

→29

LHS ≠ RHS

hence

a-b ≠ b-a

Answer :

According to the question,

$\huge\bf\boxed{RHS :}$

= a - b

= (-11) - 18

-29

$\huge\bf\boxed{LHS :}$

= b - a

= 18 - (-11)

= 29

$\bf\red{- 29 ≠ 29}$

$\bf\red{T herefore, \: a ≠ b}$
