Resolver las siguientes fracciones​

Answer 1

Respuesta:

$\frac{3x}{4x - 1} = 2$

$3 x = 2(4x - 1)$

$3x = 8x - 2$

$2 = 8x - 3x$

$2 = 5x$

$\frac{2}{5}= x$

------------------

$\frac{x + 1}{ \times - 1} = \frac{7}{5}$

$(x + 1)5 = 7(x - 1)$

$5x + 5 = 7x - 7$

$5 + 7 = 7x - 5x$

$12 = 12x$

$\frac{12}{12} = x$

$1 = x$
