Answer 2

Answer:

$\left( x - y \right) + \left( y - x \right) + \left( 2 y - x \right) = - x + 2 y$

Step-by-step explanation:

$\left( x - y \right) + \left( y - x \right) + \left( 2 y - x \right)$

$\gray{\mathrm{ R e m o v e \: p a r e n t h e s e s } : \quad \left( a \right) = a }$

$= x - y + y - x + 2 y - x$

$\gray{\mathrm{ G r o u p \: l i k e \: t e r m s }}$

$= x - x - x - y + y + 2 y$

$\gray{\mathrm{ A d d \: s i m i l a r \: e l e m e n t s : } \: x - x - x = - x}$

$= - x - y + y + 2 y$

$\gray{\mathrm{ A d d \: s i m i l a r \: e l e m e n t s : }\: - y + y + 2 y = 2 y }$

$= - x + 2 y$
