$\"S=4Y-160\"$
\n" ); document.write( "and
\n" ); document.write( " $\"S%2BY=90\"$
\n" ); document.write( "Substitute,
\n" ); document.write( " $\"4Y-160%2BY=90\"$
\n" ); document.write( " $\"5Y=250\"$
\n" ); document.write( " $\"Y=50\"$
\n" ); document.write( "So then,
\n" ); document.write( " $\"S%2B50=90\"$
\n" ); document.write( " $\"S=40\"$ \r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
