Combine y and 3y to get 4y.
![\tt \: 4y=0+24](https://tex.z-dn.net/?f=%20%5Ctt%20%5C%3A%204y%3D0%2B24%20)
Add 0 and 24 to get 24.
![\tt \: 4y=24](https://tex.z-dn.net/?f=%20%5Ctt%20%5C%3A%204y%3D24%20)
Divide both sides by 4.
![\tt \: y=\frac{24}{4} \\](https://tex.z-dn.net/?f=%20%5Ctt%20%5C%3A%20y%3D%5Cfrac%7B24%7D%7B4%7D%20%20%5C%5C%20)
Divide 24 by 4 to get 6.
