\n" ); document.write( "
\n" ); document.write( "(d) + (3d + 12) = 36
\n" ); document.write( "
\n" ); document.write( "d + 3d + 12 = 36
\n" ); document.write( "
\n" ); document.write( "4d + 12 = 36
\n" ); document.write( "
\n" ); document.write( "4d = 24

\n" ); document.write( "Mother's age = 3d + 12 = 3(6) + 12 = 18 + 12 = 30
