To determine who is correct, we can first simplify the equation using substitution.
Let's solve the equation x-15=12-8 using substitution.
x-15 = 12-8
x-15 = 4
Now, we can solve for x by adding 15 to both sides of the equation:
x = 4 + 15
x = 19
Since Mikayla's solution matches the result we calculated, Mikayla is correct. Jesse's answer of x=27 is incorrect.
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)
