Question

Rezolvati ecuatiile:
5+2+2x+1)=5(x-1)

5(x+3)+2=3(x+9)

6(3x+1)+4=2(10x+1)+4

25•(x+1)+3=24x+35

121+6•(x+2)=4(x+2)+139

(x+1)•10+1=9•(x+2)

12(2x+3)=3(7x+1)+39
Repede va rog!!!!!! Nu am mult timp!

Answer 1

5+4x+2=5x+5⇒7-5=5x-4x⇒x=2
5x+15+2=3x+27⇒5x-3x=27-17⇒2x=10⇒x=5
18x+6+4=20x+2+4⇒10-6=20x-18x⇒4=2x⇒x=2
25x+25+3=24x+35⇒25x-24x=35-28⇒x=7
121+6x+12=4x+8+139⇒6x-4x=147-133⇒2x=14⇒x=7
10x+10+1=9x+18⇒10x-9x=18-11⇒x=7
24x+36=21x+3+39⇒24x-21x=42-36⇒3x=6⇒x=2
primul ex., vezi dc e scris corect
