Explicación paso a paso:
[tex] \frac{x}{3} - \frac{1}{4} = \frac{1}{3} - \frac{x}{4} \\ \frac{x}{3} \times \frac{4}{4} = \frac{4x}{12} \\ \frac{1}{4} \times \frac{3}{3} = \frac{3}{12} \\ \frac{1}{3} \times \frac{4}{4} = \frac{4}{12} \\ \frac{x}{4} \times \frac{3}{3} = \frac{3x}{12} \\ \frac{4x}{12} - \frac{3}{12} = \frac{4}{12} - \frac{3x}{12} \\ \frac{4x - 3}{12} = \frac{4 - 3x}{12} \\ 4x - 3 = 4 - 3x \\ 3x + 4x = 4 + 3 \\ 7x = 7 \\ x = \frac{7}{7} = 1[/tex]
espero te sirva
