Question

3 (x-3)=-12 ajuda por favor??????????????​

Answer 1

Resposta: -1

( 3 x - 9 ) - { - 12 } = 0

3 x + 3 = 0

( 3 ) ⋅ x + ( 3 ) = 0

x =- ( 3 )3

x = -( 3 )( 3 )= - 1

Answer 2

Resposta:

$\huge\boxed{ \bf{x = - 1}}$

Explicação passo-a-passo:

$\bf{3(x - 3) = - 12}$

$\bf{3x - 9 = - 12}$

$\bf{3x = - 12 + 9}$

$\bf{3x = - 3}$

$\bf{x = \frac{ - 3}{3} }$

$\boxed{ \bf{x = - 1}}$
