Ran in:
For a numerical approach:
https://www.mathworks.com/help/matlab/math/systems-of-linear-equations.html
% coefficient matrix
A = [1 0 0 0 0 0;
1 1 0 0 1 0;
7 6 1 0 5 1;
19 13 5 1 9 3;
25 12 8 4 7 3;
16 4 4 4 2 1];
% sums
b = [0.25 0 0 0 0 0].';
% solve for variables
x = A\b
x = 6×1
0.2500 -2.0000 1.0000 -1.0000 1.7500 0.5000
