1. $\"5x-3y=35\"$
\n" ); document.write( "2. $\"y=x-y\"$
\n" ); document.write( "Re-arrange eq. 2,
\n" ); document.write( "2. $\"y=x-y\"$
\n" ); document.write( " $\"2y=x\"$
\n" ); document.write( " $\"x=2y\"$
\n" ); document.write( "Substitute for x with this expression and solve for y in eq. 1,
\n" ); document.write( "1. $\"5x-3y=35\"$
\n" ); document.write( " $\"5%282y%29-3y=35\"$
\n" ); document.write( " $\"10y-3y=35\"$
\n" ); document.write( " $\"7y=35\"$
\n" ); document.write( " $\"highlight%28+y=5%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"x=2y\"$
\n" ); document.write( " $\"x=2%285%29\"$
\n" ); document.write( " $\"highlight%28+x=10%29\"$ \n" ); document.write( "

\n" );
