This is APE after adding 2OH ULT
d. If 4m = 12. then 2m = 6
This is DPE after dividing both sides by 2.
EXERCISES:
Instruction: Identify the property illustrated in each statem
C
1. If a +5 = 14, then a + 10 = 19.
2. If d + e = f, then d + e - 9 = f-9.
3. If b + c = 11, and b = 3, then 3 + c = 11.
4. m + n = n + m
5. If k + x = 7, then k = 7 - X​
