The image appears to contain a series of mathematical expressions and equations that are written upside down. I will interpret and rewrite them as they should appear to help analyze the content accurately:

1. $x + y = 10$ and $12x + 5y = 64$ (labeled as "(c)")
2. $b = 4 + 8v = d$ and $u = \frac{m}{p}$ (labeled as "(b)")
3. $9 - t \cdot z = w$ and $p \cdot d = 10$ (labeled as "(d)")
4. $8 = f \cdot h = w$ and $12 = z \cdot d$

Additionally, there is a note mentioning "find all values" at the bottom.

To proceed with solving these equations:

• Would you like me to solve each system for specific variables, or are there any particular equations you would like to focus on?
• Some parts may need clarification, such as whether certain terms represent constants or variables.

Let me know if you'd like further clarification, detailed solutions, or an explanation of specific steps.

Here are some additional questions that might expand on this topic:

1. Do you want the values for each variable across all the equations?
2. Would you like assistance in solving each equation step-by-step?
3. Are any of the equations part of a specific mathematical topic or system you’re studying?
4. Should I assume that each equation represents a separate system, or should they be solved collectively?
5. Are there constraints or values already known for any of the variables?

Tip: When dealing with multiple equations, it's often helpful to solve for one variable in terms of another to simplify each equation step-by-step.
