Solve the system:
I'm trying to learn this on my own, and I know the answer to this problem is "none" ... but can someone tell me how I figure that?
And, what exactly does it mean by "solve the system" ?
find the values of x and y by any of various methods: graphing, substitution, addition / elimination, matrices, Cramer's Rule, etc.
The "none" solution means that there is no set of values for x and y that would make both equations true at the same time. If you try to solve the system by whatever method, you will end up with a nonsensical result, such as "2 = 0".
