2-(3х+2)=5-2х

2-3(х+2)=5-2х

0,2-2х-2=0,4

5(2+1,5)-0,5=24

7х=3(х+8)

Answer 1

2-(3х+2)=5-2х -6х+4=5-2х -6х+2х=5-4 -4х=4 х=-1 0,2-2х-2=0,4 -2х=0,4+2-0,2 -2х=2,2 х=-1,1 7х=3(х+8) 7х=3х+8 7х-3х=8 4х=8 х=2

Answer 2

2-(3х+2)=5-2х
2-3х-2-5+2х=0
-х-5=0
-х=5
х=-5


2-3(х+2)=5-2х
2-3х-4-5+2х=0
-7-х=0
-х=-7
х=7

0.2-2х-2=0.4
0.2-2х-2-0.4=0
-2.2-2х=0
-2х=2.2
х=-1.1

7х=3 (х+8)
7х=3х+24
7х-3х=24
4х=24
х=6
