I see that the document contains several mathematical problems designed for a unit test, mainly focused on solving equations and inequalities. Here's an overview of the first few problems:

1. **Inequality problem**: Solve \( -2 \leq 2x + 4 < 18 \) and represent it on a number line.
   
2. **Double inequality**: Solve \( 2(x - 2) \geq 10 \geq \frac{x}{2} + 5 \) and show the solution on a number line.

3. **Simultaneous equations**:
   - \( 3y + 9 = 3x \)
   - \( 6x^2 + 5y = -1 \)

4. **Fractional equation**: Solve \( \frac{2y + 3}{3y - 1} = \frac{4}{5} \) to find the value of \( y \).

5. **Another set of simultaneous equations**:
   - \( 5y = 7x + 1 \)
   - \( 4x^2 + 3y - 17 = 0 \)

Would you like me to solve any of these problems in detail? If so, let me know which one you'd like to start with!

Here are five related questions to explore further:

1. How do you solve and graph compound inequalities like problem 1?
2. What is the general method for solving simultaneous equations?
3. How do you isolate variables when dealing with fractional equations?
4. What role does factoring play in solving quadratic simultaneous equations?
5. Can inequalities define the region of a shape, like the pentagon mentioned in problem 8?

**Tip:** When solving inequalities, always consider whether dividing or multiplying by negative numbers flips the inequality sign!

Solve the inequality −2 ≤ 2x + 4 < 18, show your solution on a number line.

Learn how to solve the compound inequality −2 ≤ 2x + 4 < 18 and graph the solution on a number line. This problem focuses on key algebraic concepts and the rules for solving inequalities. Suitable for students in Grades 10-11.
