Kayla and Riley both solved the equation x-15 = 13-7, using substitution. Kayla says the answer is x=21, and Riley says that answer is x=28. Which student is correct?(1 point) Responses Kayla Kayla Riley Riley Neither Neither Both

Answer 1

To verify which student is correct, we can solve the equation using substitution:

x - 15 = 13 - 7

Simplifying both sides of the equation:

x - 15 = 6

Now, let's solve for x:

x = 6 + 15

x = 21

Therefore, Kayla is correct and the answer is x = 21.
