The summer monsoon generally begins in April and lasts through late September, while the winter monsoon arrives

At first you have to write the variables out which are
![3x + 2y + 5x + 3y](https://tex.z-dn.net/?f=3x%20%2B%202y%20%2B%205x%20%2B%203y)
now you have to combine like terms
![3x + 5x = 8x](https://tex.z-dn.net/?f=3x%20%2B%205x%20%3D%208x)
![2y + 3y = 5y](https://tex.z-dn.net/?f=2y%20%2B%203y%20%3D%205y)
now you add these two variables and end up with answer of
After reviewing the graph you have given with the question, there are several reasons why carbon 14 can't be used to accurately determine the age of organic remains that are 1 million years old.
