1.) –2х+5=–5 
-2х=-5-5 
-2х=-10 
х=-10:(-2) 
х=5 
2.) 6–5х=2х+5 
-5х-2х=5-6 
-7х=-1 
х=-1:(-7) 
х=1/7 
3.) 2(х+1)=3 
2х+2=3 
2х=3-2 
2х=1 
х=1:2 
х=0,5 
4.) 5(х–2)=2х 
5х-10=2х 
5х-2х=10 
3х=10 
х=10:3 
х=10/3 или 3 целых 1/3 
5.) –5(3–х)=2х+7 
-15+5х=2х+7 
5х-2х=7+15 
3х=22 
х=22:3 
х=22/3 или 7 целых и 1/3 
6.) 9–2(3–4х)=–2х+1 
9-6+8х=-2х+1 
8х+2х=1-9+6 
10х=-2 
х=-2:10 
х=-1/5 
7.) 9+2(3–4х)=3х–3 
9+6-8х=3х-3
