Решите уравнения: А)2x-3(x-1)=4+2(x-1)Б)x/3+x+1/4=2

А) 2x - 3(x - 1) = 4 + 2(x - 1) ;2х - 3х + 3 = 4 + 2х - 2 ;2х - 3х - 2х = 4 - 2 - 3 ;-3х = - 1 ;х = -1 : (-3) ;х = 1/3 .Ответ : 1/3 .Б) x/3 + x + 1/4 = 2 ;х/3 + х = 2 - 1/4 ;(х * 1 + х * 3)/3 = (2 * 4 - 1 * 1)/4 ;4х/3 = 7/4 ;4х * 4 = 7 * 3 ;16х = 21 ;х = 21 : 16 ;х = 21/16 ;х = 1 5/16.Ответ : 1 5/16.
