#-22y+16z#

First, let's distribute the #-4# to the terms in the parenthesis to get

#color(steelblue)(2y)+color(purple)(20z)color(steelblue)(-24y)color(purple)(-4z)#

We can group our like terms to get

#color(steelblue)(2y-24y)+color(purple)(20z-4z)#

This simplifies to

#color(steelblue)(-22y)+color(purple)(16z)#

Hope this helps!
