Решите уравнение: 1: -2(5x-2)-(3x+4)=-(8x-1)+2(6x+10) 2: 4x-(-5x)+10-(-2)=-(-4)+x 3: -2x+4x-(-8)-5=-5x-11+(-3)

1) 2(5х-2)-(3х+4)=(8х-1)+2(6х+10) 10х-4-3х+4=8х-1+12х+20 10х-3х-8х-12х=-1+20+4-4 -13х=19 х= 19:(-13) х= -1 6/13 2) 4х-(-5х)+10-(-2)=-(-4)+х 4х+5х+10+2=4+х 4х+5х-х=4-10-2 8х= -8 х= -8:8 х= -1 3) -2+4х-(-8)-5=-5х-11+(-3) -2х+4х+8-5= -5х-11-3 -2х+4х+5х= -11-3+5-8 7х= -17 х= -17:7 х= - 2 3/7
