2) 2

3)2(7x-7)

Вот такой ответ , график думаю сам нарисуешь

Answer 2

Ответ:

Пошаговое объяснение:

-7 - 4x = -10x - 6

10x - 4x = -6 + 7

6x = 1

x = 1 : 6

x = 1/6

================

5(x - 5) = -8x + 1

5x - 25 = -8x + 1

5x + 8x = 1 + 25

13x = 26

x = 26 : 13

x = 2

=============

2(7x - 7) = 7(2x - 3) + 7

14x - 14 = 14x - 21 + 7

14x - 14 = 14 - 14

14x - 14x = 14 - 14

0 = 0

x є (-∞ ; ∞)

==============

(x - 3)/6 = (7 - x)/3

6*(7 - x) = 3*(x - 3)

42 - 6x = 3x - 9

3x + 6x = 42 + 9

9x = 51

x = 51 : 9

x = 5 2/3
