Solving Systems With Algebra Tiles
- positive and negative x- tiles and y- tiles
- positive and negative unit tiles
| In this activity, you will use algebra tiles to solve systems of equations by substitution and by elimination using multiplication. |
What follows below is an example of using algebra tiles to solve a system of equations by substitution.
1. Use tiles to represent this system of equations.

2. Describe how you would solve the first equation for x. What is your result?
|
||||
| 3. Represent the result with
tiles, and sketch it in the space below. |
 |

| 4. Use the tiles that represent x in the equation from Exercise 3 and substitute them for x in the second equation. Since the second equation calls for 2x, you will need to double the tiles that represent x. Sketch your result in the diagram. |  |
