Question

Решите уравнения. Помогите пожалуйста

Answer 1

1) |9y| = 0 ⇔ 9y = 0 ⇔ y = 0/9 ⇔ y = 0
2) |x - 5| = 0 ⇔ x - 5 = 0 ⇔ x = 5
3) |3x - 1| = 0 ⇔ 3x - 1 = 0 ⇔ 3x = 1 ⇔ x = 1/3
4) |7x - 2| = 0 ⇔ 7x - 2 = 0 ⇔ 7x = 2 ⇔ x = 2/7
5) |5x - 4| = 0 ⇔ 5x - 4 = 0 ⇔ 5x = 4 ⇔ x = 4/5
6) |10x - 1| = 0 u⇔ 10x - 1 = 0 ⇔ 10x = 1 ⇔ x = 1/10 ⇔ x = 0,1
