Question

If x + y = 13 and y = 2, then which of the following is true according to the substitution property? Question 1 options: A) x + 2 = 13 B) y = 13 – x C) x = 13 – y D) 2 + y = 13

Answer 1

x+2=13

Step-by-step explanation:I took the test

Answer 2

A.

Explanation:

Since y=2, we can place 2 where y is, giving us the equation:

x+2=13

(And as a bonus, to solve this subtract 2 from each side, making x=11. If you were to graph the answer, you would have the point (11,2))
