Х/3 - х/4 =1/6 общ.знамен. 12
4х - 3х=2
х=2

х/4=х- 1/6 общ.знамен. 12
3х=12х -2
12х-3х=2
11х=2
х=2/11

(х+6)/2 =(4+х)/3 общ.знамен. 6
3(х+6)=4(4+х)
3х+18=16+4х
4х-3х=18-16
х=2

(3+х)/8=х/5
5(3+х)=8х
15+5х=8х
8х-5х=15
3х=15
х=5

(х+2)/6=(1+х)/8
8(х+2)=6(1+х)
8х+16=6+6х
2х= -10
х=-5

(2х-3)/5=(х-2)/3
3(2х-3)=5(х-2)
6х-9=5х-10
х= -1
