To determine who is correct, let's first solve the equation x - 9 = 16 using substitution.
Mikayla's solution:
Let x = 19.
Then, 19 - 9 = 16.
So, Mikayla's solution is x = 19.
Jesse's solution:
Let x = 27.
Then, 27 - 9 = 16.
So, Jesse's solution is x = 27.
Both Mikayla and Jesse's solutions work for this equation. Therefore, both students are correct as x can be either 19 or 27.
In conclusion, both Mikayla and Jesse are correct, and the equation x = 16 has multiple solutions (x = 19 and x = 27).
Mikayla and Jesse both solved the equation x
15128, 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.
