Step-by-step explanation:

Answer:
-4z-7
You use distributive proprety to get rid of the five, then combined 6z and -10z which = -4z-7
Take a look at my notes. I hope this helps.
see below
8x and 56 are not like terms
x is a variable and 56 is a constant
8x can be added to 56 but they cannot be combined together into one term
8x+56 cannot be combined because they are not like terms
x=136°
x=180°-(180-(46+90))
x=180-44
x=136
