Invalid Dimension

[charmanderp]

When I try to solve simultaenous equations on my Classpad 330, using the function in 2D, whenever I input the equations and then ask to solve for a variable I get an error saying 'invalid dimension'. Any idea why?

It means you're entering it wrong - could you just screenshot what you're entering (or if you don't know how to screenshot, just take a pic with a camera/phone or something) - because I've seen the error before, but don't remember exactly how to fix it - need to see

I'll Facebook it to you.

Could you suggest some equations for me to fit in?

[paulsterio]

Yeah, sure, sounds good.

Hmm, let me think of one that's nice and easy:





There you go Unless there was a specific set of equations which gave it trouble.

No, pretty much anything D:

Done.

If you're still having trouble with this solve for all the variables in the set of equations instead of just one

I managed to solve it with the help of Paul but thanks for posting the solution here for everyone to see! Should have done that myself.
