Tap a term to subtract it from both sides of a balanced equation until x stands alone or vanishes, then sort the result: one solution, no solution, or every x.
An equation sits on a balance, one side per pan. Tapping a term subtracts it from both pans at once, tapping a lone coefficient divides both sides, and tapping a bracket expands it — every move is a legal step, so there are many reduction paths. Reduce until x stands alone (x = a, one solution), or x disappears leaving a false statement (a = b, no solution) or a true one (a = a, every x), then sort the equation into its bin; the three endings look different (the beam tips on ≠, glows ∞ on an identity). A build mode flips it: dial the right side to force a chosen outcome. It targets the misconception that every equation has exactly one answer and the habit of guessing the verdict before reducing. Best for Grade 8 (8.EE.7a).
