You can put this solution on YOUR website! 2 -3 1 0
1 0 0 1
0 -1 1 1
3 1 2 -4
---
put the system of linear equations into standard form
---
2x - 3y + 1z + 0u = 0
1x + 0y + 0z + 1u = 0
0x - 1y + 1z + 1u = 0
3x + 1y + 2z - 4u = 0
---
copy and paste the above standard form linear equations in to this solver:
