Question

5x mas 2 sobre 3 igual a 7 (x menos 4)​

Answer 1

Explicación paso a paso:

$5x + \frac{2}{3} = 7(x - 4) \\ \\ 5x + \frac{2}{3} = 7x - 28 \\ \\ 5x - 7x = - 28 - \frac{2}{3} \\ \\ - 2x = \frac{ - 84 - 2}{3} \\ \\ - 2x = - \frac{86}{3} \\ \\ x = - \frac{86}{3} \div ( - 2) \\ \\ x = \frac{86}{6} \\ \\ x = \frac{43}{3}$
