−3x + 5 − 4 ∙ (x − 1) = −2 ∙ (x + 1) − 24

Răspuns :

-3x + 5 -4x +4 =-2x - 2 - 24
-7x + 5 + 4 = -2x -2 -24
-7x + 9 = -2x - 26
-7x +2x = -26 - 9
-5x = 35
x= 7

Rezolvare:

-3x+5-(4×x-4×1)= ( -2×x -2×1)-24

-3x+5-4x-4= -2x-2-24

-3x-4x+2x= -5+4-2-24

-7x-4x= -1-26

-9x= -27

x= -27: (-9)

x= 3 :))))

Sper ca ti-am fost de ajutor ;)))
