A student said that x = 4 was not a solution to the question 3(x -6) = -8
Here is their work:
3(x -6) = -8
3 (4 -6) = -8
12 -6 = -8
6≠-8
so x = 4 is not a solution
Did the student substitute x=4 correctly? How do you know?
Did the student simplify with Order of Operations correctly? How do you know?
If you try the problem, what do you get when you substitute x=4 into the equation?
