These web-based activities were developed, during summer sessions from 1997 through 1999, by students at Mainland High School, located in Daytona Beach, FL. As part of Mainland's CCTT grant, the students were given permission by the book's publisher to convert the ancillary materials of the County's adopted Algebra 1 Textbook into html format.
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. |  |

5. Describe how you would solve this equation for y. What is the result?
