Let's solve each of the problems step-by-step from the image.

### Problem 9:
\[
2 \left( \frac{x}{2} - 2 \right) - 3(x + 1) = 
\]

Step 1: Distribute the 2 and the -3:
\[
2 \cdot \left(\frac{x}{2}\right) - 2 \cdot 2 - 3 \cdot x - 3 \cdot 1
\]
\[
= x - 4 - 3x - 3
\]

Step 2: Combine like terms:
\[
(x - 3x) + (-4 - 3) = -2x - 7
\]

The answer to Problem 9 is:
\[
-2x - 7
\]

### Problem 10:
\[
6 \left( \frac{x}{3} + 1 \right) - 4(2x - 3) =
\]

Step 1: Distribute the 6 and the -4:
\[
6 \cdot \frac{x}{3} + 6 \cdot 1 - 4 \cdot 2x + 4 \cdot 3
\]
\[
= 2x + 6 - 8x + 12
\]

Step 2: Combine like terms:
\[
(2x - 8x) + (6 + 12) = -6x + 18
\]

The answer to Problem 10 is:
\[
-6x + 18
\]

### Problem 11:
\[
-(3x - 4) - 10\left( \frac{x}{5} + 1 \right) =
\]

Step 1: Distribute the -1 and the -10:
\[
-3x + 4 - 10 \cdot \frac{x}{5} - 10 \cdot 1
\]
\[
= -3x + 4 - 2x - 10
\]

Step 2: Combine like terms:
\[
(-3x - 2x) + (4 - 10) = -5x - 6
\]

The answer to Problem 11 is:
\[
-5x - 6
\]

### Problem 12:
\[
\frac{1}{2}(a + 2b) - \frac{1}{3}(3a - b) =
\]

Step 1: Distribute the \(\frac{1}{2}\) and \(\frac{1}{3}\):
\[
\frac{1}{2}a + \frac{1}{2}(2b) - \frac{1}{3}(3a) + \frac{1}{3}b
\]
\[
= \frac{1}{2}a + b - a + \frac{1}{3}b
\]

Step 2: Combine like terms:
\[
\left(\frac{1}{2}a - a\right) + \left(b + \frac{1}{3}b\right) = -\frac{1}{2}a + \frac{4}{3}b
\]

The answer to Problem 12 is:
\[
-\frac{1}{2}a + \frac{4}{3}b
\]

### Problem 13:
\[
-\frac{1}{4}(5x - 3y) + y =
\]

Step 1: Distribute the \(-\frac{1}{4}\):
\[
-\frac{1}{4} \cdot 5x + \frac{1}{4} \cdot 3y + y
\]
\[
= -\frac{5}{4}x + \frac{3}{4}y + y
\]

Step 2: Combine like terms:
\[
-\frac{5}{4}x + \left( \frac{3}{4}y + y \right) = -\frac{5}{4}x + \frac{7}{4}y
\]

The answer to Problem 13 is:
\[
-\frac{5}{4}x + \frac{7}{4}y
\]

### Problem 14:
\[
3x - 6\left( \frac{x}{2} + \frac{1}{3} \right) - 4(x - 1) =
\]

Step 1: Distribute the -6 and the -4:
\[
3x - 6 \cdot \frac{x}{2} - 6 \cdot \frac{1}{3} - 4x + 4
\]
\[
= 3x - 3x - 2 - 4x + 4
\]

Step 2: Combine like terms:
\[
(3x - 3x - 4x) + (-2 + 4) = -4x + 2
\]

The answer to Problem 14 is:
\[
-4x + 2
\]
