Let's break down the puzzle based on the image.

You are asked to solve the value of each shape in the given number puzzle. Here's how the equations involving shapes work:

1. First Equation: $2 + \text{Diamond} = 7$
   This implies:
   $\text{Diamond} = 7 - 2 = 5$

2. Second Equation: $\text{Diamond} - \text{Triangle} = 1$
   Since the diamond equals 5, this becomes:
   $5 - \text{Triangle} = 1$
   $\text{Triangle} = 5 - 1 = 4$

3. Third Equation: $\text{Triangle} + \text{Hexagon} = 13$
   We already know that the triangle equals 4, so this becomes:
   $4 + \text{Hexagon} = 13$
   $\text{Hexagon} = 13 - 4 = 9$

4. Fourth Equation: $\text{Triangle} + \text{Diamond} + \text{Diamond} =$
   Using $\text{Triangle} = 4$ and $\text{Diamond} = 5$, we substitute:
   $4 + 5 + 5 = 14$

Therefore, the values of the shapes are:

• Diamond = 5
• Triangle = 4
• Hexagon = 9
