va rog.va implor ajutati ma trb sa predau maine.dau coroana
2x-12=0
-x+5=0
-13x-26=0
2,1y-6,3=0

-4x+28=0
2(x+3)-5=x-7
4(x+8)=3(x-2)
5x-3(×-1)=4-x​

Answer 1

2x-12=0=>2x=12=>x=6

-x+5=0=>-x=-5=>x=5

-13x-26=0=>-13x=26=>x=-2

2,1y-6.3=0=>2,1y=6,3=>y=3

-6y-18=0=>-6y=18=>y=-3

-10x+1=0=>-10x=-1=>10x=1=>$x=\frac{1}{10}$

11y-4y=6-(-15),y€Z =>7y=21=>y=3

x+2x+3x=-42,x€N =>6x=42=>x=7

-4x+28=0=>-4x=-28=>x=7

2(x+3)-5=x-7=>2x+6-5=x-7=>2x+1=x-7=>x=-8

4(x+8)=3(x-2)=>4x+32=3x-6=>x=-6-32=-38

5x-3(x-1)=4-x​=>5x-3x+3=4-x=>2x+3=4-x=>3x=1=>$x=\frac{1}{3}$

Bafta!
