Variable Vault – Easy

What this puzzle is: solve each small algebra clue to uncover a number. Each correct number “unlocks” part of the vault. Solve them all to open it fully.

How to approach:

  • Read one clue at a time — don’t try to solve everything at once.
  • If it says solve, isolate the variable step-by-step.
  • If it says simplify, expand brackets and collect like terms first.
  • Write each answer clearly before moving on.

Tip: treat each clue as a mini standalone puzzle — accuracy matters more than speed.
