You can put this solution on YOUR website!
I suggest elimination.
\n" ); document.write( "Subtract eqns 2 & 3, you get an eqn in x & y.
\n" ); document.write( "Multiply eqn 2 by 3, then add eqn 1 --> another eqn in x & y.
\n" ); document.write( "------
\n" ); document.write( "Now it's 2 eqns in 2 variables.
\n" ); document.write( "
\n" ); document.write( "
\n" );
