Question 820043: Solve the system of equations
1) x+y+z+w=2
2x-3z= 5
x-2y+ 4w= 9
x+y+ 2z+ 3w= 5
2) x-y= 3
2x+y= 6
x-2y= 9
3) x-y+z-w= 0
3x-y-z-w= 2 Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! Linear system 1:
---
x + y + z + w = 2
2x - 3z = 5
x - 2y + 4w = 9
x + y + 2z + 3w = 5
