Answer:
addition property of equality.
multiplication property of equality.
Explanation:
Starting with x/3 - 7 = 18, we want to solve for x.
We add 7 to each side by using the addition property of equality.
x/3-7+7 = 18+7
x/3 = 25
Now multiply each side by 3 using the multiplication property of equality.
x/3 * 3= 25*3
x = 75
