I see that you've uploaded three images with several exercises on solving equations. Let's go through the problems step by step and find the solutions.

### From the first image:
**Exercise 2D, Problem 1** asks:
"If \(x = 3\), are the following equations true or false?"

1. **(a) \(5 + 2x = 4x - 1\)**
   \[
   \text{Substitute } x = 3: \quad 5 + 2(3) = 4(3) - 1
   \]
   \[
   5 + 6 = 12 - 1 \quad \Rightarrow \quad 11 \neq 11
   \]
   **False**

2. **(b) \(7x = 6x + 5\)**
   \[
   \text{Substitute } x = 3: \quad 7(3) = 6(3) + 5
   \]
   \[
   21 = 18 + 5 \quad \Rightarrow \quad 21 = 23
   \]
   **False**

3. **(c) \(2 + 8x = 12x\)**
   \[
   \text{Substitute } x = 3: \quad 2 + 8(3) = 12(3)
   \]
   \[
   2 + 24 = 36 \quad \Rightarrow \quad 26 \neq 36
   \]
   **False**

4. **(d) \(9x - 7 = 3x + 11\)**
   \[
   \text{Substitute } x = 3: \quad 9(3) - 7 = 3(3) + 11
   \]
   \[
   27 - 7 = 9 + 11 \quad \Rightarrow \quad 20 = 20
   \]
   **True**

### Continuing with the next set of exercises in **Exercise 2D, Problem 4**:
Let's focus on solving the equations. I can proceed similarly for each of the uploaded images and problems. Would you like me to continue solving in this manner, or would you prefer specific sections from any of the images? Let me know if you have any questions about these solutions or want more examples explained!

#### 5 Questions:
1. What would be the solution to \(2t + 8 = 8t + 20\)?
2. Can you solve \(4 + 3n = 10n + 39\)?
3. Is it possible to solve \(5x + 8 = 6x - 1\)?
4. How would you simplify and solve \(9t + 4 = 4j + 14\)?
5. Can \(6t - 3 = 7t - 8\) be simplified, and what is the solution?

**Tip:** When substituting values into an equation, ensure all terms are calculated correctly before comparing both sides.

The original images submitted contain multiple algebraic equations asking for verification and solution.

Step-by-step solutions for verifying and solving linear equations. This problem set includes exercises where you substitute values to verify the truth of equations and solve for unknown variables. Suitable for students in Grades 7-9.
