\n" ); document.write( "Let x = number of years until father will be 3 times as old as son
\n" ); document.write( ".
\n" ); document.write( "From the statement of the problem, we get our equation:
\n" ); document.write( "41+x = 3(9+x)
\n" ); document.write( "41 + x = 27 + 3x
\n" ); document.write( "41 = 27 + 2x
\n" ); document.write( "14 = 2x
\n" ); document.write( "7 = x
\n" ); document.write( ".
\n" ); document.write( "Therefore, in 7 years the man will be three times as old as the son.
