If you follow the problem description literally with f for Father and a for Ali present ages, and simplify the resulting system of equations, you can form \"system%28f-5a=-30%2Cf-2a=7%261%2F2%29\" .\r

\n" ); document.write( "\n" ); document.write( "You should find \"a=12%261%2F2\" and \"f=20\" .\r
\n" ); document.write( "
