2x-3•(x+1)/2=-1​

Answer 1

Resposta:

$x = - 2$

Explicação passo-a-passo:

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