Provide an appropriate response.After working correctly through several steps of the solution of a linear equation, a student obtains the equation 6x = 5x. Then the student divides each side by x to get 6 = 5 and gives ? as the answer. Is this correct? If not, explain why.
What will be an ideal response?
Answers will vary. This is not correct to divide by a variable. If -5x is added to both sides, the equation becomes -x = 0, so x = 0 and {0} is the correct solution set.
