You can put this solution on YOUR website!

system%28x+%2B+y+%2B+2z+=+1%2C%0D%0A-2x+-+4y+%2B+2z+=+7%2C%0D%0A10x+-+17y+%2B+13z+=+8%29

I will assume you meant for the 2nd term in the third equation to be 
  -17y, not -17x

Since you did not tell us the method you are studying, I will just give
you the answer. If you want to know how to solve this system, just tell
us which method you are studying.

Answer:

system%28x=-267%2F176%2C+y=+-51%2F176%2C+z=247%2F176%29

In case you actually meant -17x for the 2nd term in the 3rd equation, the
solution is

system%28x=21%2F32%2C+y=-51%2F32%2C+z=31%2F32%29
