Answer 1

Respuesta:

$4 - 6x + 12 = 4x \\ 4 + 12 = 4x + 6x \\ 16 = 10x \\ x = \frac{16}{10} = \frac{8}{5} \\ \\ 4 - 6 \times \frac{8}{5} + 12 = 4 - \frac{48}{5} + 12 = 4 \times \frac{8}{5} \\ \frac{20}{5} - \frac{48}{5} + 12 = \frac{32}{5} \\ \frac{ - 28}{5} + \frac{60}{5} = \frac{32}{5} \\ \frac{32}{5} = \frac{32}{5}$
