\"5s-2t=1-a\"
\n" ); document.write( "\"-8s%2Bbt=4\"
\n" ); document.write( "If they have infinitely many solutions then the first equation is a multiple of the second.
\n" ); document.write( "\"5s-2t=alpha%28-8s%2Bbt%29\"
\n" ); document.write( "and
\n" ); document.write( "\"1-a=alpha%284%29\"
\n" ); document.write( "Using the coefficient for \"s\",
\n" ); document.write( "\"5s=alpha%28-8s%29\"
\n" ); document.write( "\"alpha=-5%2F8\"
\n" ); document.write( "So then,
\n" ); document.write( "\"1-a=%28-5%2F8%294\"
\n" ); document.write( "\"1-a=-5%2F2\"
\n" ); document.write( "\"a=1%2B5%2F2\"
\n" ); document.write( "\"highlight%28a=7%2F2%29\"\r
