{[-3·(-x-1)-16]:(-2=0​

Răspuns :

Salut.

[-3 × (-[tex]\displaystyle{x}[/tex] - 1) - 16] ÷ (-2) = 0

-3 × (-[tex]\displaystyle{x}[/tex] - 1) - 16 = 0 × (-2)

-3 × (-[tex]\displaystyle{x}[/tex] - 1) - 16 = 0

-3 × (-[tex]\displaystyle{x}[/tex] - 1) = 0 + 16

-3 × (-[tex]\displaystyle{x}[/tex] - 1) = 16

-[tex]\displaystyle{x}[/tex] - 1 = 16 ÷ (-3)

-[tex]\displaystyle{x}[/tex] - 1 = -5,(3)

-[tex]\displaystyle{x}[/tex] = -5,(3) + 1

-[tex]\displaystyle{x}[/tex] = -4,(3)

[tex]\boxed{x = 4,(3)}[/tex]

(3x-13):-2=0

3x-13=0x(-2)

3x-13=0

3x=13

x=13:3

x=4,(3)
