4

Not sure what you need with just “4.” If you want, I can give a quick 4-question practice set. Here’s a 4-question algebra mini-quiz with solutions:

1. Solve for x: 3x + 7 = 2x − 5

• Solution: x = −12

2. Solve for x: (2x − 3)/(x + 4) = 5

• Solution: 2x − 3 = 5x + 20 → −3x = 23 → x = −23/3

3. Factor and solve: x^2 − 5x + 6 = 0

• Solutions: x = 2 or x = 3

4. Simplify (4x^2 − 12x)/(2x) for x ≠ 0

• Simplification: (4x(x − 3))/(2x) = 2(x − 3) = 2x − 6

If you tell me your subject and level, I’ll tailor a 4-question set (or any length) to that topic. Want more problems, or a different topic?
