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
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
