X=2.. start off with the numbers you know then do trial and error with the options you have
Answer:
-26z - 15
Step-by-step explanation:
tp simplify an expression, you combine all the things with z in them and all the plain numbers. In this case you have a negative 20z and a negative 6 z, which makes negative 26z. The only number is -15 so there's nothing to combine with that. Put the pieces together and you have -26z-15
