Criteria for Success
Understand that if an equation has no solution, then there is no value for x that will make the equation true
Understand that if an equation has infinite solutions, then x can represent any value and it will make the equation true
Understand that if an equation has a unique solution, then there is one value for x that will make the equation true

Open Ended
Todd and Jason both solved an equation and ended up with this final line in their work:
−2x=4x.
Todd says, “This equation has no solution because −2≠4.”
Jason says, “The solution is −2 because −2(−2)=4.”
