Question

Select the property of equality used to arrive at the conclusion if x-3=7 , then x=10

Answer 1

Answer:

The addition property of equality  

Step-by-step explanation:

According to the addition property of equality, if we add the same number to each side of an equation, the equality is still true.

We are given the equation

x – 3 = 7, and we must solve for x.

We want to get x by itself, so we add 3 to each side.

x – 3 + 3 = 7 + 3

             x = 10

We have just used the addition property of equality.
