Chain Reaction – Medium

Carry your labels consistently: if Step 2 says “use your answer from Q1 as a”, make sure you keep using that exact label.

  • Write “Given a = …” at the top of the next step.
  • Substitute once, then simplify.
  • Box the final result and rename it exactly as the puzzle requests (b, c, d…).

Tip: if you ever end up with awkward numbers, pause and re-check the previous step — Medium chains often stay fairly neat.
