You can put this solution on YOUR website!
$\"5x%2Bz=y\"$ ------eqn. 1
\n" ); document.write( " $\"-y%2B2x=3=-z\"$ ------eqn. 2
\n" ); document.write( " $\"3x%2B4y=18\"$ ------eqn. 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "From eqn. 2,\r
\n" ); document.write( "\n" ); document.write( " $\"3=-z\"$
\n" ); document.write( "Therefore,
\n" ); document.write( " $\"z=-3\"$ \r
\n" ); document.write( "\n" ); document.write( "Did you say \"solve for z\"? \n" ); document.write( "
