See the entire solution process below:

First, expand the terms in parenthesis. Be sure to pay attention to the signs of the terms as you expand:

#3y - 4(3z - 2y) - 2z -> 3y - (4 xx 3z) - (4 xx 2y) - 2z ->#

#3y - 12z - 8y - 2z#

Next, group like terms together:

#3y - 8y - 12z - 2z#

Now, combine like terms:

#(3 - 8)y + (-12 - 2)z ->#

#-5y - 14z#
