Question

1/2 + 4/3 a + 2/3 a = 2/9 + a

Answer 1

Respuesta:

$\frac{1}{2} + \frac{4}{3} a + \frac{2}{3} a = \frac{2}{9} a$

ordenamos

$\frac{4}{3} a + \frac{2}{3} a - \frac{2}{9} a = - \frac{1}{2}$

$\frac{6}{3} a - \frac{2}{9} a = - \frac{1}{2}$

$\frac{16}{9} a = - \frac{1}{2} \\ a = - \frac{9}{32}$

respuesta 9/ 32
