Four years ago, I was half as old as my father. Six years hence, I will be three fifths as old as he. How old I am now?
\n" ); document.write( "

Let my age be M, and my father's, F
\n" );
document.write( "Then 4 years ago, F - 4 = 2(M - 4)_____F = 2M - 4
\n" );
document.write( "Then in 6 years' time, we get: 
\n" );
document.write( "5M + 30 = 3(2M + 2) ------ Multiplying by LCD, 5 
\n" );
document.write( "5M + 30 = 6M + 6
\n" );
document.write( "5M - 6M = 6 - 30
\n" );
document.write( "- M = - 24
\n" );
document.write( "M, or my age is:  \n" );
document.write( "

\n" );
