Given:
- Total major pollen sources: 53
- Categories: Grasses (G), Weeds (W), Trees (T)

You've already determined that:
- **Number of grasses (G) = 12**

Using the relationships provided:
1. **Weeds (W)** are 9 less than twice the number of grasses:
   $$
   W = 2G - 9 = 2(12) - 9 = 24 - 9 = 15
   $$
2. **Trees (T)** are 2 more than twice the number of grasses:
   $$
   T = 2G + 2 = 2(12) + 2 = 24 + 2 = 26
   $$

**Summary of Major Pollen Sources in State A:**
- **Grasses:** 12
- **Weeds:** 15
- **Trees:** 26

These numbers add up to the total:
$$
12\ (\text{Grasses}) + 15\ (\text{Weeds}) + 26\ (\text{Trees}) = 53
$$

**Answer:** The number of weeds in state A is 15.
The number of weeds in state A is 15.
