Пошаговое объяснение:

13x = 36 - x

13x + x = 36

14x = 36

x = 36 : 14

x = 2 8/14

x = 2 4/7

===========

0,4x + 3,8 = 2,6 - 0,8x

0,4x + 0,8x = 2,6 - 3,8

1,2x = -1,2

x = -1

===========

4/9x + 14 = 1/6x + 9

4/9x - 1/6x = 9 - 14

8/18x - 3/18x = -5

5/18x = -5

x = -5 * 18/5

x = -18

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

4(x - 6) = x - 9

4x - 24 = x - 9

4x - x = 24 - 9

3x = 15

x = 15:3

x = 5

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

6 - 3(x + 1) = 7 - x

6 - 3x - 3 = 7 - x

3 - 3x = 7 - x

3x - x = 3 - 7

2x = -4

x = -4 : 2

x = -2

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

(8x + 3) - (10x + 6) = 9

8x + 3 - 10x - 6 = 9

-2x - 3 = 9

2x = -3 - 9

2x = -12

x = -12:2

x = -6
