Question

Помогите пожалуйста решить уравнения: (490 – Х)– 250 = 70
И (1604- Х) – 108 = 800

Answer 1

(490 - x) - 250 = 70490 - x - 250 = 70x = 240 - 70x = 170
(1604 - x) - 108 = 8001604 - x - 108 = 800x = 1496 - 800x = 696

Answer 2

(490 - x) - 250 = 70
490 - x - 250 = 70
x = 240 - 70
x = 170

(1604 - x) - 108 = 800
1604 - x - 108 = 800
x = 1496 - 800
x = 696

Answer 3

1. 490 - х = 320.
х = 490 - 320
х = 170.

2. 1604 - х = 908.
