ME AJUDE , Preciso pra amanhã isso

Answer 1

Resposta:

$\frac{ - x}{3} + \frac{2x - 3}{ 4} = - 1 \\ \\ - \frac{x}{3} + \frac{2x - 3}{4} = - 1 \\ \\ \frac{ - 4x + 3 \times (2x - 3) = - 12}{12} \\ \\ - 4x + 6x - 9 = - 12 \\ 2x - 9 = - 12 \\ 2x = - 12 + 9 \\ 2x = - 3 \\ x = - \frac{3}{2}$

$\frac{2x}{5} - \frac{x + 2}{2} = \frac{12}{10} \\ \\ \frac{4x - 5 \times (x + 2) = 12 }{10} \\ \\ 4x - 5x - 10 = 12 \\ - x - 10 = 12 \\ - x = 12 + 10 \\ - x = 22 \times ( - 1) \\ x = - 22$
