Try this:
\n" ); document.write( "Let S = Sue's present age and L = Louis's present age.
\n" ); document.write( "1) S = 7L \"Sue is 7 times as old as Louis.\"
\n" ); document.write( "2) S+6 = 5(L+6) \"In 6 years, Sue will be 5 times as old as Louis (will be in 6 years time)\" Substitute equation 1) into equation 2) and solve for L.
\n" ); document.write( "2a) (7L)+6 = 5(L+6) Simplify.
\n" ); document.write( "7L+6 = 5L+30 Subtract 5L from both sides.
\n" ); document.write( "2L+6 = 30 Subtract 6 from both sides.
\n" ); document.write( "2L = 24 Divide both sides by 2.
\n" ); document.write( "L = 12 and...
\n" ); document.write( "S = 7L
\n" ); document.write( "S = 7(12)
\n" ); document.write( "S = 84
\n" ); document.write( "
\n" );
