State whether the statements are True or False.

a – b = b – a

Take Left Hand Side of the equation.

Left Hand Side can be represented by LHS.

LHS = a – b …(i)

And then consider Right Hand Side of the same equation.

Right Hand Side can be represented by RHS.

RHS = b – a

Take minus common from RHS, we get

RHS = -(a – b) …(ii)

Now, compare equations (i) and (ii),

Notice that,

LHS = a – b and RHS = -(a – b)

This means, (a – b) ≠ -(a – b)

⇒ LHS ≠ RHS

Thus, this is a false statement.
