If the system were time-invariant, its response to x 2 ( t) should be a shifted version of its response to x 1 ( t): However, from (1) we have y 1 ( t − T) = x 1 ( − ( t − T)) = x 1 ( − t + T). Comparing this to (3) we see that (4) is not satisfied, and, consequently, the system is not time-invariant. solid wood cabinet with doors
