hey, firstly sorry for my english, I'm not from an English-speaking country

I always thought everything is possible with my Classpad 330 but:

how can i solve a term like:

[5 10 20] * X = [10 20 40]Â

Doesn't seem to be that hard, but all my attempts to solve this term failed.

Thanks

That is strange that is should be difficult to solve with the classpad330. I just did it in a fraction of a heart beat with the TI Voyage 200 as follows:
solve([5,10,20]*x=[10,20,40],x) and the answer returned is x=2, which is obviously correct.
Perhaps you didn't enter the problem correctly?
