1. $\"y-x=17\"$
\n" ); document.write( "2. $\"y=4x%2B2\"$
\n" ); document.write( "Substitute eq. 2 into eq. 1,
\n" ); document.write( " $\"4x%2B2-x=17\"$
\n" ); document.write( " $\"3x%2B2=17\"$
\n" ); document.write( " $\"3x=15\"$
\n" ); document.write( " $\"highlight%28x=5%29\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"y=4%285%29%2B2\"$
\n" ); document.write( " $\"y=20%2B2\"$
\n" ); document.write( " $\"highlight%28y=22%29\"$ \n" ); document.write( "
