Question

resuelve las siguientes ecuaciones de 2 grados​

Answer 1

$\frac{x}{3} + \frac{4}{15} - x = \frac{1}{6} - \frac{7x}{10} \\ \frac{x}{3} - x + \frac{7x}{10} = \frac{1}{6} - \frac{4}{15} \\ \frac{10x - 30x + 21x}{30} = \frac{15 - 24}{90} \\ \\ \frac{x}{30} = \frac{ - 9}{90} \\ x = \frac{ - 9}{90} \times 30 \\ x = - 3$
