Given that:

x is greater than y

minimum value of stack z = y

Prove that:

x is greater than (minimum value of stack z)

The following properties may be helpful:

if a = b, then b = a
if y = minimum value of stack z, then x is greater than y = x is greater than (minimum value of stack z)
if the following are true:
- a
- a = b
then b

Please write your proof in the table below. Each row should contain one claim. The last claim is the statement that you are trying to prove.
