-4x + 3y + 3z = -209
-6x - y - 8z = -209
-9x + 4y - 7z = -418
Make a simple equation from elimination.
-4x + 3y + 3z = -6x- y - 8z
2x + 4y + 11z = 0
-4x + 3y + 3z = -209
4x + 8y + 22z = 0
11y + 25z = -209
Make another simple equation.
-36x - 6y - 48z = -1254
-36x + 16y - 28z = -1672
-22y - 20z = 418
Solve for "z" with the 2 simple equations and then subsitute in simple equations for the solution of "y".
22y + 50z = -418
-22y - 20z = 418
30z = 0
z = 0
11y + 25(0) = -209
y = -19
Subsitute "y" and "z" and solve for "x".
-6x + 19 = -209
-6x = -228
x = 38
(38, -19, 0).
418 + 523 + 12 = 953.
