Read each question carefully and follow the instructions. Show all your work for full credit.

1. Which of the following equations has infinitely many solutions?

3x + 5 = 3x - 2

2(x + 4) = 2x + 8

5x - 10 = 15

x + 7 = x - 7

2. An equation has no solution if, after simplifying, you end up with:

A true statement (e.g., 5 = 5)

A false statement (e.g., 0 = 7)

x = a constant (e.g., x = 3)

x = x

3. The equation 6x - 4 = 2(3x - 2) has exactly one solution.

True

False

4. If an equation simplifies to 0 = -5, it has no solution.

True

False

5. An equation that is always true, no matter the value of the variable, has solutions.

6. When solving an equation, if you arrive at a contradiction like 10 = 8, the equation has solution.

7. Determine if the equation 4x - 8 = 4(x - 2) has one solution, no solution, or infinitely many solutions. Explain your reasoning.

8. For what value of 'a' would the equation ax + 5 = 3x + 5 have infinitely many solutions? Justify your answer.

9. Consider the system of equations: y = 2x + 3 y = 2x - 1 Describe what the graphs of these two equations would look like and explain what that implies about the number of solutions for the system. Draw them on the graph below.

Match each equation type with its characteristic.
