I can now see the image. It contains several math problems. Let's extract and solve each one:

1. $\frac{3}{4} x = 12$
2. $13 = 6k$
3. $k + 4 = 13$
4. $11 = -6 + k$
5. $12 = -4 + f$
6. $20 = 4n$

Let's begin solving each of these equations step by step.Here are the solutions to the equations:

1. $\frac{3}{4}x = 12$ → $x = 16$
2. $13 = 6k$ → $k = \frac{13}{6}$ (approximately 2.17)
3. $k + 4 = 13$ → $k = 9$
4. $11 = -6 + k$ → $k = 17$
5. $12 = -4 + f$ → $f = 16$
6. $20 = 4n$ → $n = 5$

Let me know if you need further clarifications or more details.

Here are 5 related questions to deepen your understanding:

1. How do you solve equations with fractions like $\frac{3}{4}x = 12$?
2. What is the process of isolating a variable in an equation like $13 = 6k$?
3. How can you check if your solution to an equation is correct?
4. What strategies can be used to solve equations involving negative numbers, such as $11 = -6 + k$?
5. How does distributing affect solving equations like $20 = 4n$?

Tip: Always check your solutions by substituting the values back into the original equations.
