Answer:
1). SUBTRACTION property of equality
2). MULTIPLICATION property of equality
Explanation:
Step 2:
When we subtract the same number from both the sides of an equation it represents the subtraction property of equality.
Here 5 has been subtracted from both the sides.
Therefore, SUBTRACTION property of equality was applied.
Step 4:
If the same number is multiplied to both the sides of an equation, multiplication property of equality is applied.
Here 4 has been multiplied to both the sides.
Therefore, MULTIPLICATION property of equality was applied.
