Mikayla and Jesse both solved the equation x - 15 - 12 - 8, using substitution. Mikayla says the answer is x = 19, and Jesse says the answer is x = 27. Which student is correct, and how do you know? Show your work and explain your thinking. (2 points)

Answer 1

To solve the equation x - 15 - 12 - 8 using substitution, we first need to simplify the equation:

x - 15 - 12 - 8
= x - 35

Now, we substitute x = 19 into the equation:

19 - 35
= -16

Now, we substitute x = 27 into the equation:

27 - 35
= -8

Therefore, neither Mikayla nor Jesse is correct. The correct answer is x = 35.
