Решите уравнения: 10x-5=6(8x+3)-5x 21=-20-8(2x-0,5) (4-8,,8x+1)=5 -8(11-2x)+40=3(5x-4) 8(5x-1)=0

10x-5=6(8x+3)-5x 

10х-5=48х+18-5х

10х-48х+5х=18+5

-33х=23

х=-23/33

21=-20-8(2х-0,5)

21=-20-16х+4

21=-16-16х

16х=-16-21

16х=-37

х=-37/16      х=-2  5/6

(4-8,2х)-(3,8х+1)=5

4-8,2х-3,8х-1=5

-12х=5-4+1

х=-2/12     х=-1/6

-8(11-2х)+40=3(5х-4)

-88+16х+40=15х-12

16х-15х=-12+48

х=36

8(5х-1)=0

40х-8=0

40х=8

х=8/40

х=1/5
