Re: system
There are no real solutions. Substituting y from the second equation into the first will yield a quartic with no real roots.

Re: system
Hi Shiiro;
Jane is of course correct. Since you posted this in "help me", I assume that you didn't know the answer or how to get an informed opinion. First thing you can do is graph the equations.

Pretty clear that their is no intersection in R^2 possible, so no real solutions. You should graph whenever possible.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
