How did you get that though @stargirlzilin

I'm almost certain he or she did zero computation to get that

anonymous · Answer

I used matrices and the calculator. 
If you know linear algebra or know how to use matrices, the problem isn't too bad.

It took you quite a while to post that solution. You didn't want to explain initally. Posting the answer first does not help the student. Guiding the student is the only thing that helps. If you post an answer again like that, I'm going to report you @stargirlzilin
