Пошаговое объяснение:

3(x- 4) = 5(2x - 3)

3x - 12 = 10x - 15

10x - 3x = 15 - 12

7x = 3

x = 3 : 7

x = 3/7

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

3x * 4 = 2(3 + x)

12x = 6 + 2x

12x - 2x = 6

10x = 6

x = 6 : 10

x = 6/10

x = 3/5

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

6(3 - x) = 4(x + 5)

18 - 6x = 4x + 20

4x + 6x = 18 - 20

10x = -2

x = -2 : 10

x = -2/10

x = -1/5
