Question

x-3 -3x-2 şi *+2 +0,(6)=2x- 3 5 10​

Answer 1

Explicație pas cu pas:

$0,(6) = \dfrac{6}{9} = \dfrac{2}{3}$

$\dfrac{x + 2}{3} + \dfrac{2}{3} = \dfrac{2 - x}{5} - \dfrac{x - 3}{10}$

$\dfrac{x + 2 + 2}{3} = \dfrac{^{2)} 2 - x}{5} - \dfrac{x - 3}{10}$

$\dfrac{x + 4}{3} = \dfrac{4 - 2x - x + 3}{10}$

$10(x + 4) = 3(7 - 3x)$

$10x + 40 = 21 - 9x$

$19x = -19 \implies x = - 1$
