Question

$\frac{2}{5} (5x - 1) + \frac{3}{10} (10 \times 3) = - \frac{1}{2} (x - 2) - \frac{6}{5}$
Ayúdame Sebas ​

Answer 1

Explicación paso a paso:

$\frac{2}{5} (5x - 1) + \frac{3}{10} (10 \times 3) = - \frac{1}{2} (x - 2) - \frac{6}{5}$

$2x - \frac{2}{5} + \frac{3}{10} \times 30 = - \frac{1}{2} x + 1 - \frac{6}{5}$

$2 x - \frac{2}{5} + 3 \times 3 = - \frac{1}{2} x - \frac{1}{5}$

$2x - \frac{2}{5} + 9 = - \frac{1}{2} x - \frac{1}{5}$

$2x + \frac{43}{5} = - \frac{1}{2} x - \frac{1}{5}$

$20x + 86 = - 5 x - 2$

$20 x + 5x = - 2 - 86$

$25x = - 88$

$x = - \frac{88}{25}$

$x = - 3.52$

Espero haberte ayudado ;)
