SOLUTION: How do you know when an equation has no solution? My answer was when you get two different answers on opposite sides of the equation. Can you help me to determine this answer?

You can put this solution on YOUR website!
Hello There,
if an equasion has infinite solutions, that means that you can put any number into the missing parts (variables, question marks, blanks) and it will equal itself or the same number every time.
example:
2x=2x
if you put in any number for x, and do the equasion, then you will get one number=itself. that means that it has infinite solutions.
if it has no solution you will get an untrue answer. like 5=3
when you see something like 5=3, it has no solution because 5 cannot equal 3. only 5=5 and 3=3. not 5=3.
hope that helped..
