1. The problem is to create a math quiz with multiple questions.
2. Let's design a quiz with three algebra problems involving solving equations and simplifying expressions.
**Question 1:** Solve for $x$ in the equation $$2x + 5 = 15$$.
**Solution:**
- Subtract 5 from both sides: $$2x = 15 - 5$$
- Simplify: $$2x = 10$$
- Divide both sides by 2: $$x = \frac{10}{2} = 5$$
**Question 2:** Simplify the expression $$3(x - 4) + 2x$$.
**Solution:**
- Distribute 3: $$3x - 12 + 2x$$
- Combine like terms: $$3x + 2x - 12 = 5x - 12$$
**Question 3:** Solve for $y$ in the quadratic equation $$y^2 - 4y - 5 = 0$$.
**Solution:**
- Factor the quadratic: $$(y - 5)(y + 1) = 0$$
- Set each factor equal to zero:
- $$y - 5 = 0 \Rightarrow y = 5$$
- $$y + 1 = 0 \Rightarrow y = -1$$
This quiz covers solving linear equations, simplifying expressions, and solving quadratic equations.
