Trina planted 7 zucchini(z) plants, 14 cucumber(c) plants, and 22 tomato(t) plants. This is the case because 43-8=35, you subtract 8 because of the extra tomatoes, then using zucchini as a checkpoint you have 1z 2c's and 2t's, total that's 5 equal parts. Then just divide 35 by 5 to get 7 so you know you have 7 zucchini, which means you have 14 cucumber and 22 tomatoes.
