\n" ); document.write( "Six years ago Kris daughter's age = x-6 and Kris age = 3x -6
\n" ); document.write( "3x-6 = 5(x-6)
\n" ); document.write( "3x-6 = 5x - 30
\n" ); document.write( "2x = 30 -6
\n" ); document.write( "2x = 24
\n" ); document.write( "x = 12
\n" ); document.write( "Kris age = 3*12 = 36
