Fill in the Blank

A logistics business owner models delivery time variables (xx, yy, and zz) using the system of linear equations:

{2x2y+3z=64x3y+2z=02x+3y7z=1\left\{\begin{array}{l} 2x - 2y + 3z = 6 4x - 3y + 2z = 0 -2x + 3y - 7z = 1 \end{array}\right.

She applies the elimination method to solve the model. First, she eliminates the variable xx. Adding the first and third equations yields y4z=7y - 4z = 7. Next, multiplying the third equation by 2 and adding it to the second equation yields 3y12z=2{}3y - 12z = 2.

To eliminate yy from this new sub-system, she multiplies the first equation by -3 and adds it to the second. This completely removes the variables and results in the false numerical statement 0=19{}0 = -19.

Because this process results in a false numerical statement, the system has no solution. A system of linear equations that has no solution is classified as ____.
