Answer 1

Zad.1
3/x-2= 4/2x+1
6x+3=4x-8
6x-4x=-8-3
2x=-11
x=-5,5

spr:
3/(-5,5)-2=4/2*(-5,5)+1
3/(-7,5)=4/(-11)+1
-0,4=4/(-10)
-0,4=-0,4


Zad.2
2/3=3x+2/2x-2
4x-4=9x+6
4x-9x=6+4
-5x=10
x=-2

spr:
⅔=3*(-2)+2/2*(-2)-2
⅔=-6+2/-4-2
⅔=-4/-6
⅔=⅔


Zad.3
6x-1/x+1=2,3/1,2
7,2x-1,2=2,3x+2,3
7,2x-2,3x=2,3+1,2
4,9x=3,5
x=⁵/₇

spr:
6*⁵/₇-1/⁵/₇+1=2,3/1,2
4²/₇-1/1⁵/₇=1¹¹/₁₂
3²/₇/1⁵/₇=1¹¹/₁₂
1¹¹/₁₂=1¹¹/₁₂
