There are two types of variables which are used for scientific experiments.

Explanation:
From the attached image, we are giving a clue that there are 5 Hibiscus flowers.
So, each symbol of the Hibiscus flower is 5.
1st row: Hibiscus + Tree = 14
⇒ 5 + Tree = 14
∴ Tree = 14 - 5 = 9
This means that the tree represents 9
2nd row: Sunflower + Hibiscus = 13
⇒ Sunflower + 5 = 13
∴ Sunflower = 13- 5 = 8. This means that the sunflower represents 8.
3rd row: Tree - sunflower = 9-8 = 1
4th row: Sunflower + tree = 9+8 = 13
Last row: Hibiscus(5) × Sunflower(8) ≠ Tree (9)
