Week 2 Concept Check Post your 50-word response to the following: • How do you know when an equation has infinitely many solutions? • How do you know when an equation has no solution?

An equation has an infinite number of solutions when the variable equals itself. For example, x=x, both sides are equal. No matter what values are given for x the terms of the equation will always be met. If an equation has no solution you will get an untrue answer such as 6=2 when you see something like 6=2, it has no solution because 6 cannot equal 2. Only 6=6 and 2=2.
