Решите уравнения:

10x-5=6 (8x+3) - 5x

21=-20-8 (2x-0,5)

(4-8,2x) - (3,8x+1) = 5

-8 (11-2x) + 40=3 (5x-4)

8 (5x-1) = 0

10x-5=6 (8x+3) - 5x

10 х-5=48 х+18-5 х

10 х-48 х+5 х=18+5

-33 х=23

х=-23/33

21=-20-8 (2 х-0,5)

21=-20-16 х+4

21=-16-16 х

16 х=-16-21

16 х=-37

х=-37/16 х=-2 5/6

(4-8,2 х) - (3,8 х+1) = 5

4-8,2 х-3,8 х-1=5

-12 х=5-4+1

х=-2/12 х=-1/6

-8 (11-2 х) + 40=3 (5 х-4)

-88+16 х+40=15 х-12

16 х-15 х=-12+48

х=36

8 (5 х-1) = 0

40 х-8=0

40 х=8

х=8/40

х=1/5
