Let's work through the questions one by one from your uploaded image.

### 1. Solve and graph the solution set on a number line:
\[
\frac{4x - 3}{6} \geq \frac{2x - 1}{12} - 2
\]

#### Step 1: Simplify both sides
Multiply both sides by 12 to eliminate denominators:
\[
12 \cdot \frac{4x - 3}{6} \geq 12 \cdot \left( \frac{2x - 1}{12} - 2 \right)
\]
This simplifies to:
\[
2(4x - 3) \geq 2x - 1 - 24
\]
\[
8x - 6 \geq 2x - 25
\]

#### Step 2: Combine like terms
Move all terms involving \(x\) to one side and constant terms to the other:
\[
8x - 2x \geq -25 + 6
\]
\[
6x \geq -19
\]

#### Step 3: Solve for \(x\)
\[
x \geq -\frac{19}{6}
\]

### Graph:
- Draw a number line with an open circle at \(-\frac{19}{6}\), shading everything to the right, as the inequality is \(x \geq -\frac{19}{6}\).

### Solution:
\[
x \geq -\frac{19}{6}
\]
In interval notation: 
\[
\left[ -\frac{19}{6}, \infty \right)
\]

### 2. Solve and give solution in interval notation. Graph solution on a number line.

#### (a) \(-9 \leq 3x + 3 < 21\)

#### Step 1: Solve for \(x\)
First, subtract 3 from all parts of the inequality:
\[
-9 - 3 \leq 3x < 21 - 3
\]
\[
-12 \leq 3x < 18
\]

Now, divide by 3:
\[
-4 \leq x < 6
\]

### Solution:
In interval notation: 
\[
[-4, 6)
\]
Graph: Closed circle at -4, open circle at 6, shading in between.

---

#### (b) \(5x - 3 \leq x + 1 \ \text{or} \ -4x \leq -8\)

##### For \(5x - 3 \leq x + 1\):
\[
5x - x \leq 1 + 3
\]
\[
4x \leq 4 \quad \Rightarrow \quad x \leq 1
\]

##### For \(-4x \leq -8\):
Divide by -4, and reverse the inequality:
\[
x \geq 2
\]

### Solution:
Since this is an "or" inequality, the solution is:
\[
(-\infty, 1] \cup [2, \infty)
\]
Graph: Shaded from \(-\infty\) to 1 (closed circle), and from 2 to \(\infty\) (closed circle).

---

### 3. Solve: \(|2x - 1| = |-3x + 4|\)

#### Step 1: Consider two cases for absolute value

##### Case 1: \(2x - 1 = -3x + 4\)
\[
2x + 3x = 4 + 1 \quad \Rightarrow \quad 5x = 5 \quad \Rightarrow \quad x = 1
\]

##### Case 2: \(2x - 1 = 3x - 4\)
\[
2x - 3x = -4 + 1 \quad \Rightarrow \quad -x = -3 \quad \Rightarrow \quad x = 3
\]

### Solution:
\[
x = 1 \quad \text{or} \quad x = 3
\]

---

### 4. Solve and graph the solution set on a number line. Give solutions in interval notation.
\[
| -3x + 7 | < 11
\]

#### Step 1: Break the absolute value into two inequalities

\[
-11 < -3x + 7 < 11
\]

#### Step 2: Solve the inequality
Subtract 7 from all parts:
\[
-11 - 7 < -3x < 11 - 7
\]
\[
-18 < -3x < 4
\]

Now divide by -3 (and reverse the inequalities):
\[
\frac{-18}{-3} > x > \frac{4}{-3}
\]
\[
6 > x > -\frac{4}{3}
\]

### Solution:
\[
\left( -\frac{4}{3}, 6 \right)
\]
Graph: Open circles at \(-\frac{4}{3}\) and 6, shading in between.
