If the father's age is four times the current sum of the children's ages, x, then
\n" ); document.write( "the father's age can be represented by 4x.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In 8 years, the father's age will be 4x + 8.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The sum of the children's ages will be x + 24, since each of the three children will be 8 years older.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the father's age will be twice the sum of the children's ages, you can write:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x + 8 = 2(x + 24)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x + 8 = 2x + 48\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "4x - 2x + 8 = 48\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x + 8 = 48\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x = 48 - 8\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x = 40\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The current age of the man is 4x = 4(20) = 80 years old.
