Answer 1

Olá, bom dia!

Resposta:

$\color{blue}{\boxed{\boxed{\boxed{\mathsf{\color{red}{x=-1}}}}}}$

Explicação passo-a-passo:

$\mathsf{4x - 2 (3 + 7 x) = - 10 x - 6 ( 2x + 3)}$

$\mathsf{4x -6 -14x = - 10x -12x -18}$

$\mathsf{4x-14x+10x+12x=-18+6}$

$\mathsf{4x-4x+12x=-12}$

$\mathsf{12x=-12}$

$\mathsf{x= -\dfrac{12}{12}}$

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