A gaseous mixture consisting of 2.23 mmol N2 and 6.69 mmol H2 in a 500.-mL container was heated to 600. K and allowed to reach equilibrium. Will more ammonia be formed if that equilibrium mixture is then heated to 700. K? For N2(g) + 3 H2(g) -><- 2 NH3(g), K = 1.7 x 10^-3 at 600. K and 7.8 x 10^-5 at 700. K.

The solutions manual takes a shortcut on this question by simply comparing the equilibrium constants at the different temperatures. While I understand this answer, how would I go about solving the question with calculations instead of qualitatively?

You could use ICE box to find the concentration of each chemical, but that requires a lot of work. Comparing the equilibrium constants is a much easier way.
