+ Solve the system of equations
2x - 2y + z - w = 7
- x + 4y - 5z + 3w = 1
x + y - z + w = 4
-4x + 2y + z - 2w = 6
Commands:
=========
eq1: 2*x-2*y+z-w=7;
eq2: -x + 4*y - 5*z + 3*w = 1;
eq3: x + y - z + w = 4;
eq4: -4*x + 2*y + z - 2*w = 6;
linsolve([eq1,eq2,eq3,eq4],[x,y,z,w]);
Solution:
=========
(%i1) eq1: 2*x-2*y+z-w=7;
(%o1) z - 2 y + 2 x - w = 7
(%i2) eq2: -x + 4*y - 5*z + 3*w = 1;
(%o2) - 5 z + 4 y - x + 3 w = 1
(%i3) eq3: x + y - z + w = 4;
(%o3) - z + y + x + w = 4
(%i4) eq4: -4*x + 2*y + z - 2*w = 6;
