Add the two equations to eliminate y.
\n" ); document.write( " $\"4x+%2B+y%2B3x-y+=+25%2B20\"$
\n" ); document.write( " $\"7x=45\"$
\n" ); document.write( " $\"x=highlight%2845%2F7%29\"$
\n" ); document.write( "Then use either equation to solve for x.
\n" ); document.write( " $\"4%2845%2F7%29%2By=25\"$
\n" ); document.write( " $\"y=175%2F7-180%2F7\"$
\n" ); document.write( " $\"highlight%28y=-5%2F7%29\"$ \n" ); document.write( "

\n" );
