To solve the equation x - (-15) = 128, we can simplify the left side by adding 15 to -15 to get x + 15 = 128.
Now, we can solve for x by subtracting 15 from both sides:
x + 15 - 15 = 128 - 15
x = 113
Therefore, the correct answer is x = 113.
Both Mikayla and Jesse's answers are incorrect.
Mikayla and Jesse both solved the equation x - - 15 = 128, 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.
