\n" ); document.write( "a + b = 24
\n" ); document.write( "-----------------------------
\n" ); document.write( "in three years time, the elder brother will be twice as old as younger.
\n" ); document.write( "(a+3) = 2(b+3)
\n" ); document.write( "-----------------------------
\n" ); document.write( "how old are they ?

\n" ); document.write( "a + b = 24
\n" ); document.write( "a -2b = 3
\n" ); document.write( "------------
\n" ); document.write( "Subtract the 2nd from the 1st to get:
\n" ); document.write( "3b = 21
\n" ); document.write( "b = 7 yrs. old (Younger brother's age)
