Answer 1

$\sf \color{blue} {Olá,Milka !!}$

$\sf - 4x + 3 - 8 = x - 1 \\\sf - 4x - 5 = x - 1 \\\sf - 5 = x - 1 + 4x \\\sf - 5 = 5x - 1 \\\sf - 4 = 5x \\\sf  \red {x = - \frac{4}{5} }$

Answer 2

-4x + 3 - 8 = x - 1

-4x - 5 = x - 1

-4x = x + 4

-4x - 5 + 5 = x - 1 + 5

-5x = 4

-4x - x = x - x + 4 << -4x + 3 - 8 = x - 1

-5x/5 = 4/-5 << x = - 4/5
