You can put this solution on YOUR website!
x = 7
y = -3
2z = 6
z = 3
(7, -3, 3) is the solution

The matrix you have provided represents the following set of linear equations:
1%2Ax+%2B+0%2Ay+%2B+0%2Az+=+7 or x+=+7
0%2Ax+%2B+1%2Ay+%2B+0%2Az+=+-3 or y+=+-3
0%2Ax+%2B+0%2Ay+%2B+2%2Az+=+6 or 2z+=+6 or z+=+6%2F2+=+3

Thus we have got the values of unknowns: x = 7, y = -3, z = 3.
