Basic Math - algebra


Expert: Wei Chong - 7/9/2008

Question
I still do not understand. How do you know when an equation has infinitely many solutions? How do you know when an equation has no solution?

Answer
Hi Awilda,

To find the solution(s). You should be given 2 equations (In college, may have to deal with 3 equations). The number of solution is the number of time(s) these equations intercept each other.

Please look at that attached picture. I think the picture will explain this well.


Best Regards,
Wei Chong
