1) 4х+5(3-2х)=5 -11х; 2) 19 - 2(3х + 8)= 2х - 37; 3) 8х + 3 (7 - 2х)= 4х + 3; 4) 23 - 4 (3х + 8)= 1 - 17х.

1) 4х+5(3-2х)=5-11х
4х+15-10х=5-11х
4х-10х+11х=5-15
5х=-10
х=-2
2)19-2(3х+8)=2х-37
19-6х-16=2х-37
-6х-2х=16-19-37
-8х=-40
х=5
3) 8х+3(7-2х)=4х+3
8х+21-6х=4х+3
8х-4х-6х=3-21
-2х=-18
х=9
4)23-4(3х+8)=1-17х
23-12х-32=1-17х
17х-12х=1+32-23
5х=10
х=2 Если правильно скажи"
