Use the Gaussian elimination to find the complete solution of equation or show that none exists. 5x+12y+z=10 2x+5y+2z=-1 x+2y-3z=5

    There's no solution. Multiply the second row by two and add it to the third row. Then this combination gives us 5x + 12 y + z = 3. But the first equation is 5x + 12y + z = 10. Since 3 can never equal 10, no solution can exist.
