Question

cuál es la solución de (×-6)+12(10-4×)=×-4​

Answer 1

Respuesta:

$(x - 6) + 12(10 - 4x) = x - 4 \\ x - 6 + 12(10 - 4x) = x - 4 \\ - 6 + 12(10 - 4x) = - 4 \\ 12(10 - 4x) - 6 = - 4 \\ 12(10 - 4x) = - 4 + 6 \\ 12(10 - 4x) = 2 \\ 10 - 4x = \frac{2}{12} \\ 10 - 4x = \frac{1}{6} \\ - 4x = \frac{1}{6} - 10 \\ - 4x = - \frac{59}{6} \\ x = \frac{ - \frac{59}{6} }{ - 4} \\ x = \frac{ \frac{59}{6} }{4} \\ x = \frac{59}{6 \times 4} \\ x = \frac{59}{24}$

COMPROBACIÓN

$(x - 6) + 12(10 - 4x) = x - 4 \\ \frac{59}{24} - 6 + 12(10 - 4 \times \frac{59}{24}) = \frac{59}{24} - 4$
