Математика: 5х-4/2-2х-1/3=-1/5(х-29) 3+2х/3-(х+1/5-1-х/6)=1 2x+1/3-3+4x/9+0.5=x /=дробная черта

kira309 · Answer

(3+2х)/3 -( (х+1)/5 - (1-х)/6)=1(3+2х)/3 -( (6х+6-5+5х)/30)=1(3+2х)/3 - (11х+1)/30)=110(3+2х)-11х-1=3030+20х-11х-1=309х=30-299х=1х=1/9(2х+1)/3 - (3+4х)/9 +0,5=х3(2х+1) -3 -4х+0,5*9=9х6х+3-3-4х+4,5=9х9х-2х=4,57х=4,5х=4 1/2 :7х=9/2 * 1/7х=9/14...
