Re: Solving complicated two variable system
Hi;
Brackets are not for grouping in Mathematica, they are for functions. Change all [ to ( and all ] to ).
You have two t^2 together in the second equation?! Is that what you want?
If you post how you entered it into alpha I can run it off over here.
I will need some additional info:
1) Real roots only?
2) How many digits of precision are required.
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.

Re: Solving complicated two variable system
I just did the solve[] command in Wolfram Alpha. And it said it couldn't interpret my input. 
(1) Yes, I need Rational Roots
(2) Just round it off to the thousandths...
There should be a www.mathisnotfunatallforum.com!

Re: Solving complicated two variable system
How about the double t^2?

Re: Solving complicated two variable system
Hi;
There is only one real root
t = -2.71978301138176263225168227044*10^-6
y = 11232.0946424110872247045682968
to 30 digits of precision. Round as you need.
