Пошаговое объяснение:
б)
5/6х + 1. 2/3 = 2х - 3
5/6х - 2х = -3 - 1. 2/3
5/6х - 1. 6/6х = -4. 2/3
-1. 1/6х = -4. 2/3
-7/6х = -14/3
х = -14/3 : (-7/6)
х = -14/3 * (-6/7)
х = -2/1 * (-2/1)
х = 4/1
х = 4
в)
3/(2х - 1) = 5/(3х - 2)
3 * (3х - 2) = 5 * (2х - 1)
9х - 6 = 10х - 5
9х - 10х = -5 + 6
-х = 1
х = -1
