6(a)

The definition of time-invariant is

If the cascade

x(t)--->[time delay by t0]----->[system]-----z(t) ---(1)

yields the same output as the reverse of (a);x(t)--->[system]--->[time delay by t0]---y(t), it is called Time invariant.

When I substitute into (1) and the reverse order of (1), the results are not the same. Thus, it is not time-invariant.
