Answer 1

Resposta:

Explicação passo a passo:

$\frac{2.(x-1)}{3}+\frac{3.(1+x)}{2}=\frac{1}{2}-\frac{x-1}{3}$

$mmc(2;3)=6$

$\frac{4.(x-1)}{6} +\frac{9.(1+x)}{6} =\frac{3}{6}-\frac{2.(x-1)}{6}$

$\frac{4x-4}{6}+\frac{9+9x}{6} =\frac{3}{6}-\frac{2.(x-1)}{6}$

$\frac{13x+5}{6} =\frac{3-2.(x-1)}{6}$

$\frac{13x+5}{6} =\frac{3-2x+2}{6}$

$13x+5=-2x+5$

$13x+2x=5-5$

 $15x=0$

    $x=0/15$

    $x=0$

   $S=\{0\}$
