Judith bought 6 cookie kits and 4 house kits.

Let y represent the number of house kits and x represent the number of cookie kits.

If Judith bought a combination of  10 gingerbread house and cookie kits, hence:

x + y = 10     (1)

Also, number of house kits was one more than half the  number of cookie kits, hence:

y = (1/2)x + 1   (2)

From the graph, the solution is at (6, 4)

Hence, Judith bought 6 cookie kits and 4 house kits.
