Question

You use substitution to solve a system of equations and, after simplifying the equations, end with an expression that says 0 = 4. What does that say about the lines and about the number of solutions to the system?

Answer 1

It means there is no solution and the lines are parallel. It is called an inconsistent system.

Answer 2

Answer:

Since the statement is true, there are an infinite number of solutions to the system. This statement also indicates that the lines are equivalent. :)
