Question 592742: please help me solve this system of equations:
I tried this several different times by hand, but I can't get it. Using my graphing calculator, which also does equations, I received the following answers: x= 4.192307692, y= -1.269230769, z=3.012820513
However, I am not a calculator and I can't understand how the answer was reached. Please help me.
(As a side note, I had to transfer the answers to decimals - they were in the fractions: X= four and five twenty-sixths, Y= neg one and seven twenty=sixths, and z= three and one seventy-eighth.)
any help you can give, preferably with your work showed, would be most definitely appreciated. Thank you and God bless you for your time!

I did it on my TI-84 and got simply (x,y,z) = (4,-1,3).  Maybe you keyed
in something wrong.  If you need help ask me in the thank-you note.  I'll
email you back.  No charge. I do this for kicks.


The answer I got is correct. Here's the check:
