When you are learning vocabulary about the weather, it is important to remember that some of the words have a noun form, a verb form and/or an adjective form. For example:
Rain: (noun) The game was cancelled because of the rain.
Rain: (verb) I think it is going to rain later.
Rainy: (adjective) It's a rainy day.
It pays to learn the different forms of each word and when they are used.
1,2х - 15 = х + 15
1,2х - х = 15 + 15
0,2х = 30
х = 30 : 0,2
х = 150 кустов было на втором участке
1,2 * 150 = 180 кустов было на первом участке
ответ: 180 кустов на первом и 150 кустов на втором.
Проверка:
180 - 15 = 150 + 15
165 = 165 - стало поровну
