How do I know if this equation has any solutions or no solutions and simply could you tell me if I did the problem correct. The problem goes as follows

x-y+2z=1
5x-2y+3z=6

What you have is a partial row reduction of the matrix that was developed from your 3X3 system. The calculator stopped where it did because of the result obtained in the last line which suggests the absurd notion that 0 is equal to 1. Having obtained such a result, the calculator realized that the system has no solution.
