You can put this solution on YOUR website!
We will solve it by substitution;
\n" ); document.write( "3(\"2%2F3\")+6y=0
\n" ); document.write( "2+6y=0
\n" ); document.write( "6y=-2
\n" ); document.write( "y=-\"2%2F6\"
\n" ); document.write( "y=-\"1%2F3\"
\n" ); document.write( "Hope you understand
\n" ); document.write( "=)
\n" ); document.write( "
\n" );
