Use the expression on the left as and use Rational Roots Theorem to look for rational roots using synthetic division. The possible roots to test would be 1, 2, 3, 6, -1, -2, -3, -6.
That work or its results not being shown unless you need it. Much easier to just show the results of each root test than to include the actual synthetic divisions.
You can put this solution on YOUR website! Solve the following system of equations using
Gauss-Seidal iteration method.
27x+6y-z=85
6x+15y-2z=72
x+y+54z=110
