Proof: Do Line At Unchanged 14

Let's prove the following theorem:

if the following are true:
  • expression state at time 14 = "iterate_args"
  • the line at time 14 = 3

then the line at time 15 = 3

Given
1 expression state at time 14 = "iterate_args"
2 the line at time 14 = 3
Proof Table
# Claim Reason
1 the line at time (14 + 1) = the line at time 14 if expression state at time 14 = "iterate_args", then the line at time (14 + 1) = the line at time 14
2 the line at time (14 + 1) = 3 if the line at time (14 + 1) = the line at time 14 and the line at time 14 = 3, then the line at time (14 + 1) = 3
3 14 + 1 = 15 14 + 1 = 15
4 the line at time (14 + 1) = the line at time 15 if 14 + 1 = 15, then the line at time (14 + 1) = the line at time 15
5 the line at time 15 = 3 if the line at time (14 + 1) = the line at time 15 and the line at time (14 + 1) = 3, then the line at time 15 = 3
