<u>plug in x, y, and z.</u>
![5(-1)-(-2)[7-4(3-(-2))]](https://tex.z-dn.net/?f=5%28-1%29-%28-2%29%5B7-4%283-%28-2%29%29%5D)
![5(-1)-(-2)[7-4(5)]](https://tex.z-dn.net/?f=5%28-1%29-%28-2%29%5B7-4%285%29%5D)
![5(-1)-(-2)[7-20]](https://tex.z-dn.net/?f=5%28-1%29-%28-2%29%5B7-20%5D)
![5(-1)-(-2)[-13]](https://tex.z-dn.net/?f=5%28-1%29-%28-2%29%5B-13%5D)
![-5-(-2)[-13]](https://tex.z-dn.net/?f=-5-%28-2%29%5B-13%5D)
