The recipe calls for 2 parts borax for every 1 part soap flakes. Since Lenny is using 7 cups of soap flakes, he will need 2 * 7 = <<2*7=14>>14 cups of borax.
The recipe also calls for 2 parts washing soda for every 1 part soap flakes. Therefore, Lenny will need 2 * 7 = <<2*7=14>>14 cups of washing soda.
Therefore, Lenny needs a total of 14 + 14 = <<14+14=28>>28 cups of borax and washing soda combined. Therefore, the correct answer is 28 cups.
