\n" ); document.write( "SOLVING
\n" ); document.write( "i-ii:y-2z=14...iv
\n" ); document.write( "iii-ii:-6y=-4+8z..v
\n" ); document.write( "from eqn iv
\n" ); document.write( "y=14+2z----vi
\n" ); document.write( "put y in eqn v
\n" ); document.write( "-6(14+2z)=-4+8z
\n" ); document.write( "-84-12z=-4+8z
\n" ); document.write( "-80=20z
\n" ); document.write( "z=-4
\n" ); document.write( "from eqn vi
\n" ); document.write( "y=14+2z
\n" ); document.write( "y=14+2(-4)
\n" ); document.write( "y=6
\n" ); document.write( "X Can be found using any of the initial eqn
\n" ); document.write( "x-4y-3z=-4
