555 — want a quick drill? I can give you 5 practice questions. Here’s a short algebra set to start:

1. Solve for x: 2x − 7 = 3x + 5
2. Factor: x^2 − 5x + 6
3. Solve the system: y = 2x + 3 and y − x = 4
4. Evaluate f(x) = 3x^2 − x + 1 at x = 2
5. Mixture problem: 5 kg of a 20% solution mixed with 3 kg of a 60% solution. What is the resulting concentration?

Would you like the solutions now, or should I tailor a set to a different subject (calculus, physics, etc.)?
