\n" ); document.write( "write an equation for each statment
\n" ); document.write( "\" lisa is six years older than susan,\"
\n" ); document.write( "L = S + 6
\n" ); document.write( "or
\n" ); document.write( "S = L - 6

\n" ); document.write( ":
\n" ); document.write( "\" the total of their ages is 41\"
\n" ); document.write( "L + S + J = 41
\n" ); document.write( "replace S with (L-6); replace J with (L+5)
\n" ); document.write( "L + (L-6) + (J+5) = 41
\n" ); document.write( "3L - 1 = 41
