Proof: Multiply Substitute Two Terms 2

Let's prove the following theorem:

if the following are true:
  • a = x
  • c = y
  • s = (a + c) / m

then s = (x + y) / m

Given
1 a = x
2 c = y
3 s = (a + c) / m
Proof Table
# Claim Reason
1 (a + c) / m = (x + y) / m if c = y and a = x, then (a + c) / m = (x + y) / m
2 s = (x + y) / m if (a + c) / m = (x + y) / m and s = (a + c) / m, then s = (x + y) / m
