Question

{[-3·(-x-1)-16]:(-2=0​

Answer 1

Salut.

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

-3 × (-$\displaystyle{x}$ - 1) - 16 = 0 × (-2)

-3 × (-$\displaystyle{x}$ - 1) - 16 = 0

-3 × (-$\displaystyle{x}$ - 1) = 0 + 16

-3 × (-$\displaystyle{x}$ - 1) = 16

-$\displaystyle{x}$ - 1 = 16 ÷ (-3)

-$\displaystyle{x}$ - 1 = -5,(3)

-$\displaystyle{x}$ = -5,(3) + 1

-$\displaystyle{x}$ = -4,(3)

$\boxed{x = 4,(3)}$
