1. $\"y-4z=0\"$
\n" ); document.write( "2. $\"4x+%2B+2y+=+12\"$
\n" ); document.write( "3. $\"-x-2y%2B6z=-3\"$
\n" ); document.write( "From 1,
\n" ); document.write( " $\"y=4z\"$
\n" ); document.write( " $\"z=y%2F4\"$
\n" ); document.write( "Substitute into eq. 3,
\n" ); document.write( " $\"-x-2y%2B6%28y%2F4%29=-3\"$
\n" ); document.write( " $\"-2x-4y%2B3y=-3\"$
\n" ); document.write( "4. $\"-2x-y=-3\"$
\n" ); document.write( "From eq. 2,
\n" ); document.write( "5. $\"2x%2By=12\"$
\n" ); document.write( "Adding 4 and 5,
\n" ); document.write( " $\"-2x-y%2B2x=y=-3%2B12\"$
\n" ); document.write( " $\"0=9\"$
\n" ); document.write( "False, the system is inconsistent.
\n" ); document.write( "There is no solution.\r
