Mikayla and jesses both solved the equation x-15=12 using substitution. Mikayla says the answer is x=19, and jesse says the answer is x=27 which student is correct
To solve the equation x-15=12 using substitution, we need to isolate the variable x.
Mikayla:
x - 15 = 12
x = 12 + 15
x = 27
Jesse:
x - 15 = 12
x = 12 + 15
x = 27
Both Mikayla and Jesse got the same answer x=27. Therefore, both students are correct.
