Answer:
Addition POE
Explanation:
I believe it is the addition POE because
12x-4=44
To get 4 (the constant) to the right you have to do the inverse of subtraction which is addition. By doing so You would add 4 to both side, canceling it out on the left side and adding the 4 to the right side (44).
12x-4=44
+4 +4
12x=48
12/12=48/12
x=4
