I can't see the image you mentioned. Could you either upload it here or describe the models (how many x-tiles and how many unit tiles on each side, and which are shown as positive or negative)?

If you want to solve it yourself, use this method:
- Count x‑tiles on the left (k) and on the right (m).
- Count unit tiles on the left (a) and on the right (b), keeping track of signs (positive/negative).
- Form the equation kx + a = mx + b.
- Solve for x: (k − m)x = b − a, so x = (b − a)/(k − m).

If you post the image or the counts, I’ll solve it and pick the correct choice for you.
