Isolate the r
\n" ); document.write( "ar-3r=-6t-2
\n" ); document.write( "r(a-3)=-6t-2
\n" ); document.write( "r=-(6t+2))/(a-3)
\n" ); document.write( "I missed the ar at the beginning.
\n" ); document.write( "let r=2 and a =5
\n" ); document.write( "10+2=6-6t
\n" ); document.write( "12=-6t
\n" ); document.write( "6=-6t
\n" ); document.write( "t= -1
\n" ); document.write( "4/2=2 for r
\n" ); document.write( " \n" ); document.write( "
\n" );
