va rog ajutatima (3ori x +2):4-2=3


Răspuns :

(3×x + 2) : 4 - 2 = 3 (3×x + 2) : 4 = 2+3 (3×x + 2) : 4 = 5 3×x + 2 = 5×4 3×x + 2 = 20 3×x = 20 - 2 3×x = 18 x = 18 : 3 => x = 6
(3*x+2):4-2=3 =>(3*x+2)totul/4 -2-(3)=0 =>simplificam 3x+2totul/4=>[(3x+2)/4-2]-3=0=>
2=2/1=2*4/4
(3x*2)-(2*4)totul /4=3x-6 totul/4=>(3x-6)/4-3=0
3=3/1=3*4/4
3x-6=3*(x-2)
3*(x-2)-(3*4)totul /4=3x-18/4
3x*(x-6)totul/4=0
3*(x-6)totul/4 *4=0*4
3*(x-6)=0
3=0
x-6=0
x=6
