![\frac{4}{7x} = 21 \\](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B7x%7D%20%20%3D%2021%20%5C%5C%20)
![7x = 21 \times 4](https://tex.z-dn.net/?f=7x%20%3D%2021%20%5Ctimes%204)
![7x = 84](https://tex.z-dn.net/?f=7x%20%3D%2084)
![x = \frac{84}{7} \\](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B84%7D%7B7%7D%20%20%5C%5C%20)
