Answer:
7c - 11
Step-by-step explanation:
To solve this, you are going to need to add like terms.
Since 5 and 2 both have a "c" next to them, you can add those together to equal 7c.
Then, since -13 and 2 do not have a "c", you can combine those together to equal -7.
Since there is no = , the closest you can get to solving this equation would then be 7c - 11. 
Hope this helped!
