Which expressions correctly shows the Substitution property?

13 + 3 - 3 = 1(13 + 3 - 3)

13 + 3 - 3 = 13 + 1

13+3-3 = 18÷3

13 + 3 - 3 = 13 +3-3+0

Answer:

none of them.

Explanation:

The substitution property of equality explains that one value can replace another value in an expression or equation and the value will remain the same.

In other words if x + y = 7 and y = 5. Then I can rewrite the first statement as x + 5 = 7.

which can be solved to get x = 2. I just used the substitution property.

The first choice is the multiplicative identity property. Multiplying an expression by 1 gives the same result.

The second and third choices are wrong since 13 is not equal to 14 and neither is 13 equal to 6

The fourth choice is the additive identity property since adding zero to an expression gives the same result.

Good Luck!
