Answer:

x - 3 y + 4 z + y - 2 x - 8 z + 5 x - 2 y - 3 z = 4 x - 4 y - 7 z

Step-by-step explanation:

x - 3 y + 4 z + y - 2 x - 8 z + 5 x - 2 y - 3 z

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

= x - 2 x + 5 x - 3 y + y - 2 y + 4 z - 8 z - 3 z

\gray{\mathrm{A d d \: s i m i l a r \: e l e m e n t s : } \: x - 2 x + 5 x = 4 x}

= 4 x - 3 y + y - 2 y + 4 z - 8 z - 3 z

\gray{\mathrm{A d d \: s i m i l a r \: e l e m e n t s : }\: - 3 y + y - 2 y = - 4 y}

= 4 x - 4 y + 4 z - 8 z - 3 z

\gray{\mathrm{A d d \: s i m i l a r \: e l e m e n t s : }\: 4 z - 8 z - 3 z = - 7 z}

= 4 x - 4 y - 7 z
