![x=3](https://tex.z-dn.net/?f=x%3D3)
Step-by-step explanation:
![3x+5=14](https://tex.z-dn.net/?f=3x%2B5%3D14)
Subtract 5 from both sides:
![3x+5-5=14-5](https://tex.z-dn.net/?f=3x%2B5-5%3D14-5)
![3x=9](https://tex.z-dn.net/?f=3x%3D9)
Divide both sides by 3:
![\frac{3x}{3}=\frac{9}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B9%7D%7B3%7D)
