This should be the answer.
Answer:
![c = \frac{2a + b}{3}](https://tex.z-dn.net/?f=c%20%3D%20%5Cfrac%7B2a%20%2B%20b%7D%7B3%7D)
Step-by-step explanation:
![3c - b = 2a \\ 3c = 2a + b \\ \frac{3c}{3} = \frac{2a + b}{3} \\ c = \frac{2a + b}{3}](https://tex.z-dn.net/?f=3c%20-%20b%20%3D%202a%20%5C%5C%203c%20%3D%202a%20%2B%20b%20%5C%5C%20%20%20%5Cfrac%7B3c%7D%7B3%7D%20%20%3D%20%20%5Cfrac%7B2a%20%2B%20b%7D%7B3%7D%20%20%5C%5C%20c%20%3D%20%5Cfrac%7B2a%20%2B%20b%7D%7B3%7D)
