Provide an appropriate response.A student argued that it is impossible to use the substitution method to determine if a system of equations has no solution or an infinite number of solutions. In other words, he argued, it is possible to determine if the system has either no solution or an infinite number of solutions, but it is not possible to determine which of the two possibilities describes the system. Is the student correct? Explain.
What will be an ideal response?
No. In the case of a system that has no solution, substitution will yield a false equation (such as 3 = 0). In the case of a system that has an infinite number of solutions, substitution will yield an equation that is true for all real numbers (such as 2x + 1 = 2x + 1).
