В царстве Великой Математики жили числа. Жили они дружно и счастливо. Но была большая проблема: у каждого числа была сестричка близняшка. Долго мучились жители царства, как различить их друг от друга. В один день царица Великая Математика объявила: «Кто придумает как различить сестричек, тот будет назван гением страны».
Много приходило предложений о том как различать сестричек, но Великой математике понравился Незнайки. Он предложил всех сестричек разделить на две группы. Первая группа- отрицательные числа, вторая – положительные. Этот понравился не только Великой Математике, но и сестрам близняшкам. Незнайке дали звание гения математики. Вот так и появился интересный счет и числа разложились на две группы : положительные и отрицательные

2-я делянка - (2/5х) га всего 833 га
3-я делянка (х + 17) га
х + 2/5х + х + 17 = 833
2х = 2/5х = 833 - 17
2х +2/5х = 816
10х + 2х = 816 · 5
12х = 4080
х = 4080 : 12
х = 340
Значит, площадь первой делянки равна 340 га, второй - 2/5 · 340 = 136 (га), третьей - 340 + 17= 357 (га)
ответ: 340 га, 136 га и 357 га.
