Haveing combined ike terms you need to add 8 to both sides (Like terms are terms that have the same variable like,x)
![- x = - 5](https://img.qammunity.org/2023/formulas/mathematics/high-school/24ez9psj36atmkhj8xv4zi172kdf40skqr.png)
Then divide by a negative 1
(this is to get rid of negative x)
![x = 5](https://img.qammunity.org/2023/formulas/mathematics/college/iss9rkv919b2fefffyclchh2tnqx7dxrdh.png)
