You can put this solution on YOUR website!
Add the two equations together to remove x.
\n" ); document.write( " $\"+-2y=18\"$
\n" ); document.write( " $\"+y=9\"$
\n" ); document.write( "Then use either equation to solve for x.
\n" ); document.write( " $\"+3x-4%289%29=9\"$
\n" ); document.write( " $\"+3x-36=9\"$
\n" ); document.write( " $\"+3x=45\"$
\n" ); document.write( " $\"+x=15\"$ \n" ); document.write( "

\n" );
