Y3 = y x 3 = 4 x 3 = 12
4z = 4 x z = 4 x 6 = 24

12 + 24 - 16

Im using PEMDAS I’m not sure if you use another order of operations if you do just do the expression your way

12 + 24 = 36
36 - 16 = 20

A. 20

$-\dfrac{7}{20}+\left(-\dfrac{9}{20}\right)=\dfrac{-7}{20}+\dfrac{-9}{20}=\dfrac{-7+(-9)}{20}=\dfrac{-16}{20}=-\dfrac{16:4}{20:4}=\boxed{-\frac{4}{5}}$
