Perform row operations on the augmented matrix as far as necessary to determine whether the system is independent, dependent, or inconsistent.
\n" ); document.write( "-x - y - z = 10
\n" ); document.write( "x + y + z = -6
\n" ); document.write( "x + y - z = 2
\n" ); document.write( "A) Inconsistent
\n" ); document.write( "B) Dependent
\n" ); document.write( "C) Independent
\n" ); document.write( "------------
\n" ); document.write( "they're inconsistent since -1 times the first gives x+y+z=-10, and the 2nd says it's =6.
\n" ); document.write( "I determined that by inspection, so it wasn't necessary to do any row operations.
\n" ); document.write( "
\n" );
