6-103.

Solve each system of equations below.

1. $−4x=z−2y+12$
$y+z=12−x$
$8x−3y+4z=1$

Reorganize the equations so all of the variable terms are on one side and the constants are on the other side.

1. $3x+y−2z=6$
$x+2y+z=7$
$6x+2y−4z=12$

See part (a).

There are infinite solutions

1. What does the solution in part (b) tell you about the graphs?

Think about what this solution would mean in two dimensions. Would this mean the same thing in three dimensions?
