1)3x-1=2(x-2)
2) 3(x+5)=7-5x
3)19(y-9)=3(y+7)
4)4(x-9)=3(x-8)
5)3(2x-9)=5(x-4)
6)7(3-2x)=15(1-x)

Answer 1

1) 3х-1=2(х-2)
3х-1=2х-4
х=-3

2) 3(х+5)=7-5х
3х+15=7-5х
8х=-8
х=-1

3) 19(у-9)=3(у+7)
19у-171=3у+21
16у=192
у=12

4) 4(х-9)=3(х-8)
4х-36=3х-24
х=12

5) 3(2х-9)=5(х-4)
6х-27=5х-20
х=7

6) 7(3-2х)=15(1-х)
21-14х=15-15х
х=-6
