How do I play Solve for x?

An equation sits on a balance with x on one side. Pick an operation like − 4 or ÷ 3 · it is applied to both sides at once and the new equation appears as the next step. Keep choosing inverse operations until x stands alone.

What happens if I pick a wrong operation?

It is applied for real · the balance stays level because equality survives any same-both-sides operation, but the equation gets messier (fractions, bigger numbers). Press Undo to step back, or work your way out. Only running past the step cap loses the round.

What is the minimal path?

The smallest number of both-sides operations that isolates x, computed and proven for every equation. Clear the constant first (the inverse of + or −), then the coefficient (the inverse of × or ÷). Solving on the minimal path is the perfect round.

Why does the balance never tip?

Because that is the rule the game teaches: an equation is a balance, and applying the same operation to both sides preserves equality. Whatever you do to the left side, the game mirrors on the right · so the solution never changes, only the way the equation looks.

What does Solve for x train?

Algebraic thinking · seeing x as an unknown quantity, choosing inverse operations, and understanding that equality survives only when both sides receive the same treatment. It is the balance model behind every linear equation in school algebra.
