1. $\"3x-2y-z=1\"$
\n" ); document.write( "2. $\"2x-2y++=4\"$
\n" ); document.write( "3. $\"2x+++-2z=-12\"$
\n" ); document.write( "From 2,
\n" ); document.write( " $\"2y=2x-4\"$
\n" ); document.write( "From 3,
\n" ); document.write( " $\"2z=2x%2B12\"$
\n" ); document.write( " $\"z=x%2B6\"$
\n" ); document.write( "Substitute into 1 and solve for x.
\n" ); document.write( "1. $\"3x-2y-z=1\"$
\n" ); document.write( " $\"3x-%282x-4%29-%28x%2B6%29=1\"$
\n" ); document.write( " $\"3x-2x-x%2B4-6=1\"$
\n" ); document.write( " $\"-2=1\"$
\n" ); document.write( "Since this leads to an inconsistency, there is no solution. \r
