Плиз помогите 14+х=2
2х+х-16=2
8-17х=25
5-х=20+2х
Даю 30 балов

Answer 1

Решение и ответ:

14 + х = 2

x = 2 - 14

x = -12

2х + х - 16 = 2

3x = 2 + 16

3x = 18

x = 18 ÷ 3

x = 6

8 - 17х = 25

17x = 8 - 25

17x = -17

x = -17 ÷ 17

x = -1

5 - х = 20 + 2х

-x - 2x = 20 - 5

-3x = 15

x = 15 ÷ (-3)

x = -5
