See a solution process below:

First, terms that belong to a group:

#x - 5x - 6y - 3y + 2z + 8z#

Now, terms that belong to a group:

#1x - 5x - 6y - 3y + 2z + 8z#

#(1 - 5)x + (-6 - 3)y + (2 + 8)z#

#-4x + (-9)y + 10z#

#-4x - 9y + 10z#

To simplify the expression ( x - 6y + 2z - 5x - 3y + 8z ), combine like terms:

[ x - 5x = -4x ] [ -6y - 3y = -9y ] [ 2z + 8z = 10z ]

So, the simplified expression is ( -4x - 9y + 10z ).
