Asuperhero recently asked his nemesis how many cats she has. she answered with a riddle: "seven eights" of my cats plus two" how many cats does the nemesis have?

If the nemesis has "7/8 of her cats plus 2" it can be written like this: 7/8 x + 2 = x, where x is the number of the cats. After that we can solve the equation. x - 7/8 x = 2; 1/8 x = 2; x = 2 : 1/8 = 2 * 8 = 16. The nemesis has 16 cats.
