Michaela and Jessie both solved the equation X -15 equals 12-8 using substitution Michaela says the answer is X equals 19 and Jessie says the answer is X = 27 which student is correct and how do you know show your work and explain your thinking
To solve the equation X - 15 = 12 - 8 using substitution, we need to simplify both sides of the equation.
Michaela's solution:
X - 15 = 12 - 8
X = 12 - 8 + 15
X = 4 + 15
X = 19
Jessie's solution:
X - 15 = 12 - 8
X = 12 - 8 + 15
X = 4 + 15
X = 19
Both Michaela and Jessie arrived at the correct solution, X = 19. Therefore, both students are correct in this case.
