Answer 1

To solve x + 2 = 9 using algebra tiles, represent x with a single algebra tile and balance the equation by adding equivalent tiles on both sides. The solution is x = 3.

Step-by-step explanation:

Algebra Tiles to Solve x + 2 = 9

In order to solve the equation x + 2 = 9 using algebra tiles, you can represent x with a single algebra tile that has a value of 1. Then, you need to add 2 algebra tiles with a value of 1 each on one side of the equation to maintain balance. To keep the equation balanced, you also need to add the same number of algebra tiles on the other side of the equation. Therefore, you add 1 algebra tile with a value of 1 on the other side as well.

Now, you have 3 algebra tiles on each side of the equation, which means x = 3.
