Помогите решить уравнение, буду благодарна. 7(1-2х)=4+3(х+1) 2х-1=2(2х+1)-(х-1) 8-8х=4(х-1)-(х-6) 3(1-2х)-5(х+2)=1-4х

7(1-2х)=4+3(х+1) 7 - 14х = 4 + 3х + 3 -14х - 3х = 4 + 3 - 7 -17х = 0 х = 0 2х-1=2(2х+1)-(х-1) 2х - 1 = 4х + 2 - х - 1 2х - 4х + х = 2 - 1 + 1 -х = 0 х = 0 8-8х=4(х-1)-(х-6) 8 - 8х = 4х - 4 - х + 6 -8х - 4х + х = -4 + 6 - 8 -11х = 6 х = 6/11 3(1-2х)-5(х+2)=1-4х 3 - 6х - 5х - 10 = 1 - 4х - 6х - 5х + 4х = 1 - 3 + 10 -7х =  8 х = - 8/7
