Ответ:

Пошаговое объяснение:

a)

2x - 10 = x + 1

2x - x = 1 + 10

x = 11

=========

б)

6*(3x + 1) - 4*x = 3*(1 - x)

18x + 6 - 4x = 3 - 3x

14x + 6 = 3 - 3x

14x + 3x = 3 - 6

17x = -3

x = -3:17

x = -3/17

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

в)

2*(2 - x) + 2*10 = 5*(3 + 2x)

4 - 2x + 20 = 15 + 10x

24 - 2x = 15 + 10x

10x + 2x = 24 - 15

12x = 9

x = 9:12

x = 0,75
