Is it possible for a society to achieve equality without liberty? Explain.

No. They are tied together. If someone is considered less than equal to another person under the law, then that person will always be the so-called protected or higher person's slave. Human will to power is this way. Freedom (liberty) is ONLY possible when all people are considered equal to each other
