How do I solve a system of simultaneous equations for x?

-2.0x1 + 5.0x2 + 1.0x3 + 3.0x4 + 4.0x5 - 1.0x6 = 0.0;
2.0x1 - 1.0x2 - 5.0x3 - 2.0x4 + 6.0x5 + 4.0x6 = 1.0;

6 unknowns with 2 equations? Good luck...

Answer 1

[Walter Roberson]

A = [-2 +5 +1 +3 +4 -1;2 -1 -5 -2 +6 +4];
B = [0;1];
sols = A\B;
x1 = sols(1); x2 = sols(2); x3 = sols(3); x4 = sols(4); x5 = sols(5); x6 = sols(6);

This gives one solution out of the infinity.
