Răspuns :

[tex] \frac{x+2}{3}+ \frac{x-3}{2} =-5[/tex]

Aducem la acelasi numitor
[tex]2(x+2)+3(x-3)= -30[/tex]

[tex]2x+4+3x-9=-30 <=> 6x =-30+9-4[/tex]

[tex]5x = -25 [/tex]

[tex]=>x= \frac{-25}{5} =- 5[/tex]


X+2/3  +x-3/2=-5 , aducând la acelaşi numitor(6)  avem : 

2x+4+3x-9=-30
5x-5=-30
5x =-30+5
5x=-25
x=-25 : 5
x=-5 .
