What does this generator do?
The generator builds an equation "p · (x + q) = r" with an integer solution x. You can expand the brackets first, or divide both sides by p and then subtract q.
How to solve it
Two approaches: A) expand the brackets: "px + pq = r", so x = (r − pq) / p. B) Divide both sides by p first: "x + q = r / p", then x = r/p − q.
