Пошаговое объяснение:

2 + 3x = -7x - 5

3x + 7x = -5 - 2

10x = -7

x = -7 : 10

x = -0,7

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

7 + 8x = -2x - 5

8x + 2x = -5 - 7

10x = -12

x = -12 : 10

x = -1,2

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

-7 - 2x = -6x + 10

6x - 2x = 10 + 7

4x = 17

x = 17 : 4

x = 4,25

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

-1 - 3x = 2x + 1

2x + 3x = -1 - 1

5x = -2

x = -2 : 5

x = -0,4

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

8 - 5(2x - 3) = 13 - 6x

8 - 10x + 15 = 13 - 6x

23 - 10x = 13 - 6x

10x - 6x = 23 - 13

4x = 10

x = 10 : 4

x = 2,5
