Proof: Do Line At Unchanged 34

Let's prove the following theorem:

if the following are true:
  • expression state at time 34 = "call_returned"
  • the line at time 34 = 10

then the line at time 35 = 10

Given
1 expression state at time 34 = "call_returned"
2 the line at time 34 = 10
Proof Table
# Claim Reason
1 the line at time (34 + 1) = the line at time 34 if expression state at time 34 = "call_returned", then the line at time (34 + 1) = the line at time 34
2 the line at time (34 + 1) = 10 if the line at time (34 + 1) = the line at time 34 and the line at time 34 = 10, then the line at time (34 + 1) = 10
3 34 + 1 = 35 34 + 1 = 35
4 the line at time (34 + 1) = the line at time 35 if 34 + 1 = 35, then the line at time (34 + 1) = the line at time 35
5 the line at time 35 = 10 if the line at time (34 + 1) = the line at time 35 and the line at time (34 + 1) = 10, then the line at time 35 = 10
