Kiran and Elena play a card game.

Every time they collect a pair of matching cards, they earn x points.

At one point in the game, Kiran has -6 points and Elena has 2 points. After Kiran collects 4 pairs and Elena collects 3 pairs, they have the same number of points.

How many points do they earn each time they collect a pair of matching cards?

Thanks!
