6.6+3х=4х-1
7.-1+2х=10х+3
8.-4х+3х=8х+5

Answer 1

1.-9х-8=-8х
-9х+8х=8
-х=8
х=-8
2.-х-7=-5х
-х+5х=7
4х=7
х=7/4
3.-5х+2=-10х
-5х+10х=-2
5х=-2
х=-2/5
4.-2х+3=-8х
-2х+8х=-3
6х=-3
х=-1/2
5.-4х=-10х-9
-4х+10х=-9
6х=-9
х=-3/2
6.6+3х=4х-1
3х-4х=-1-6
-х=-7
х=7
7.-1+2х=10х+3
2х-10х=3+1
-8х=4
х=-1/2
8.-4х+3х=8х+5
-х-8х=5
-9х=5
х=-5/9
