Suppose you are an algebra teacher grading the following solution on an examination: − 3 ( x − 6 ) = 2 − x − 3 x − 18 = 2 − x − 2 x − 18 = 2 − 2 x = − 16 x = 8 You should note that 8 checks, so the solution set is (8). The student who worked the problem therefore wants full credit. Can you find any errors in the solution? If full credit is 10 points, how many points should you give the student? Justify your position.
