Question

2(x-6)=3x-4-x
3(x+5)-x=5(1-x)+2
38-6x=6+2x
​

Answer 1

Respuesta:

$2(x - 6) = 3x - 4 - x \\ 2x - 12 = 2x - 4 \\ - 12 = - 4$

No es una igualdad.

$(3x + 5) - x = 5(1 - x) + 2 \\ 3x + 15 - x = 5 - 5x + 2 \\ 2x + 15 = - 5x + 7 \\ 5x + 2x = - 15 + 7 \\ 7x = - 8 \\ x = - \frac{8}{7}$

$38 - 6x = 6 + 2x \\ 38 - 6 = 6x + 2x \\ 32 = 8x \\ \frac{32}{8} = x \\ x = 4$
