It looks like the image is from an interactive problem where algebra tiles represent an equation visually. From the image, I can see green bars (representing variables, likely $x$) and yellow squares (representing constants or units), which indicates an equation setup.

Without the ability to view the actual video, we can make some educated guesses based on the visual representation:

1. The left side shows two green bars and three yellow squares, possibly indicating $2x + 3$.
2. The options given are:
   • $2x + 3 = 9$
   • $2x - 3 = 9$
   • $2x = 18$
   • $2x + 6 = 12$

The choice of $2x + 3 = 9$ seems most likely if there are three yellow tiles on one side and nine as the solution on the other.

Would you like further clarification on this type of algebraic model or need more examples?

Here are some additional questions to consider:

1. How would you set up a similar equation if one side had a different number of tiles?
2. What if the equation involved subtraction, like $2x - 3$?
3. How can you check your answer by substitution after solving for $x$?
4. What strategy helps you quickly determine whether to add or subtract when balancing?
5. How do visual aids help in understanding abstract algebraic concepts?

Tip: Algebra tiles are a powerful way to visualize equation balancing, especially for understanding addition and subtraction of constants on both sides.
