Question

porfavor me urge´.

1-x/3 - x-1/12 = 3x-1/4

Answer 1

1 - x/3 - x - 1/12 = 3x - 1/4    (multiplicacion de todo por 12)
12 - 4x - 12x - 1 = 36x - 3
12 - 1 + 3 = 36x + 4x + 12x
14 = 52x
14/52 = x
7/26 = x

Answer 2

$1 - \frac{x}{3}-x- \frac{1}{12} = 3x - \frac{1}{4} \\ \\ 1 - \frac{1}{12}+ \frac{1}{4} = 3x +x + \frac{x}{3} \\ \\ \frac{12}{12} - \frac{1}{12}+ \frac{3}{12} = 4x + \frac{x}{3} \\ \\ \frac{14}{12} = \frac{13x}{3} \\ \\ \frac{14}{12}: \frac{13}{3} = x \\ \\ \boxed{x= \frac{7}{26} }$

Espero que te sirva, salu2!!!!
