5(7х+2у)-11у= 6(2х+у)+2
33+3(6х-5у)=3(х+2)-5у
2) 5(7х+2у)-11у= 6(2х+у)+2 1) 33+3(6х-5у)=3(х+2)-5у
35x+10y-11y=12x+6y+2 33+18x-15y-3x-6+5y=0
35x-y-12x-6y-2=0 27+15x-10y=0
-7y+23x-2=0 15x=10y-27
-7y+23*( 10y-27/15)-2=0 x=10y-27/15
-7y+230y-621/15-2=0
-105y+230y-621-30=0
125y-651=0
125y=651
y=5,208
3) x=10y-27/15
x=10*5,208-27/15
x=1,672
Ответ: x=1,672; y=5,208
