Question 116853: I can not figure out how to begin this problem let alone complete it. We are using the Gauss-Jordan Method. I refered to the website http://aspire.cs.uah.edu/textbook/gauss.html and the website http://math.uww.edu/~mcfarlat/141/141gauss.htm for assistance and thought I understood what i was doing but I can not get to the answer that is in the back of the book for this problem. The answer in the book is (1,0,-1)
The problem is as follows....
x+3y-6x=7
2x-y+2z=0
x+y+2z=-1
the first part I think I got
1 3 -6 7
2 -1 2 0
1 1 2 -1
Can you please help me.
Thank you so much!!!!!!

Question 117201: Can anyone tell me if I did this right.
x/10=9/30
Solve for x
Factors 9 and 30 have greatest common factor of 3. Reducing fraction.
It becomes x/10=3/10
Move these terms to the left - 3/10
It now becomes x/10-3/10=0
Solved linear equation x/10-3/10 equivalent to 0.1•x-0.3=0
It becomes 0=0
Solution x=3
If not can you show me where I went wrong.

Question 117512: Mrs. Lee deposited a sum of money in a savings account that pays 4% interest per year. At the end of one year, Mrs. Lee had a total of $9,620 in the account. How much did she invest originally?
I have tried multiplying the new total by 4%. The answer I was given is as follows: 9620x0.04= 384.80
That would make the initial amount ivested to be 9,235.20, which is incorrect. The answer the textbook gives me is 9,250. What exactly am I doing wrong?
