Решите уравнения:

-1,2х+5=3-0,4х

8х-1/3·(4,5х-5)=5-х

0,2/х=1 5/6 /5

DontDog -1.2x-1/3×(4.5x-5)=5-x
-1.2x+0.4x=3-5
-0.8x=-2
x=2.5

sedinalana -1,2х+5=3-0,4х
-1,2x+0,4x=3-5
-0,8x=-2
x=-2:(-0,8)
x=2,5

8х-1/3·(4,5х-5)=5-х
8x-1,5x+5/3=5-x
6,5x+x=5-5/3
7,5x=10/3
x=10/3:7 1/2=10/3*2/15
x=4/9

0,2/х=1 5/6 /5
x=0,2*5 :1 5/6
x=1*6/11
x=6/11
