\n" ); document.write( "After 15 years, his age will be only half of the sum of the children's ages.
\n" ); document.write( "Each of the 5 kids will be 15 yrs older also, therefore
\n" ); document.write( "x + 15 = .5(x + 5(15))
\n" ); document.write( "x + 15 = .5(x + 75)
\n" ); document.write( "x + 15 = .5x + 37.5
\n" ); document.write( "x - .5x = 37.5 - 15
\n" ); document.write( ".5x = 22.5
\n" ); document.write( "x = 2(22.5)
\n" ); document.write( "x = 45 is Dad's present age \n" ); document.write( "
