Do the previous equation but x is 22 y is 10 and z is 20

To proceed with the solution, let's substitute \( x = 22 \), \( y = 10 \), and \( z = 20 \) into the equation you provided.

The equation in the image was:
\[
x + y - z
\]

1. **Substitute the values:**  
   \[
   22 + 10 - 20
   \]

2. **Perform the addition and subtraction:**  
   \[
   32 - 20 = 12
   \]

### Final Answer:
\[
x + y - z = 12
\]

### Related Questions:
1. What happens if we switch the operation order for \(x\), \(y\), and \(z\)?
2. How does changing each variable by 1 unit (either up or down) affect the result?
3. What if we use a different equation form, like \(x \times y + z\)?
4. How would the result change if \(z\) were negative?
5. Can we apply these operations with functions or in more complex expressions?

### Tip:
Always check for the order of operations in an expression to ensure accurate calculations, especially when variables and multiple operations are involved.
