Пошаговое объяснение:

(2х - 7)/4 - (4х - 3)/3 = х/6 + 5/4 | * 12

3(2х - 7) - 4(4х - 3) = 2х + 15

6х - 21 - 16х + 12 = 2х + 15

-10х - 9 = 2х + 15

-10х - 2х = 15 + 9

-12х = 24

х = 24 : (-12)

х = -2

(1/6х - 1) * 6 = 3/4х - 4

х - 6 = 3/4х - 4

х - 3/4х = -4 + 6

1/4х = 2

х = 2 : 1/4

х = 2 * 4/1

х = 8/1

х = 8
