Tap tiles to strip the same x-tiles and unit tiles off both pans of a balance, cancel red −1 tiles with zero pairs, then split what remains so x stands alone — or load a different pan that balances at a given x.
An equation like 3x + 2 = x + 6 is laid out as x-tiles and unit tiles on both pans of a balance; the player taps a tile to remove that kind from both pans at once, cancels a red −1 with a zero pair by adding +1 to both pans, and finally splits the leftover units among the remaining x-tiles. Removing from one pan only tips the beam and names the move that keeps it level, and a build mode asks for a different right pan with the same weight at x = n, with many correct answers. It targets the one-sided move and the skipped negative constant. Best for Grades 7–8.
