Question

cuál es la solución de (×-6)-2×=3(4+2×)+12 plis​

Answer 1

Solución:

= x - 6-2x = 12 + 6x + 12

= x- 6 = 24 + 6x

= -x -6x = 24 + 6x

= -x - 6x = 24 + 6

- 7x = 30

x =  $\frac{- 30}{7}$

listo, si encuentras algún error en mi respuesta comentalo y la actualizaré...

Answer 2

Respuesta:

$(x - 6) - 2 = 3(4 + 2x) + 12 \\ x - 6 - 2 = 3(4 + 2x) + 12 \\ x - 8 = 3(4 + 2x) + 12 \\ x - 8 = 12 + 6x + 12 \\ x - 8 = 6x + 24 \\ - 8 = 6x + 24 - x \\ - 8 = 5x + 24 \\ -8 - 24 = 5x \\ - 32 = 5x \\ - \frac{32}{5} = x \\ x = - \frac{32}{5}$

COMPROBACIÓN

$(x - 6) - 2 = 3(4 + 2x) + 12 \\ - \frac{32}{5} - 6 - 2 = 3(4 + 2 \times \frac{ - 32}{5}) + 12 \\ - \frac{32}{5} - 6 - 2 = 3(4 + \frac{2 \times - 32}{5} + 12 \\ - \frac{32}{5} - 6 - 2 = 3(4 + \frac{ - 64}{5}) + 12 \\ - \frac{32}{5} - 6 - 2 = 3(4 - \frac{64}{5}) + 12 \\ - \frac{32}{5} - 6 - 2 = 3 \times \frac{ - 44}{5} + 12 \\ - \frac{32}{5} - 6 - 2 = \frac{3 \times - 44}{5} + 12 \\ - \frac{32}{5} - 6 - 2 = \frac{ - 132}{5} + 12 \\ - \frac{32}{5} - 6 - 2 = - \frac{132}{5} + 12 \\ - \frac{72}{5} = - \frac{132}{5} + 12 \\ - \frac{72}{5} = - \frac{72}{5}$
