Arrange the tiles on both boards to model the equation. Use the algebra tiles to model the equation
2x + 4 = 3x + (-1). Then complete the sentences.
To model 2x + 4, you need:
positive x-tiles to represent 2x.
positive unit tiles to represent 4.
To model 3x + (-1) you'll need:
3
X-tiles to represent 3x.
1
unit tile to represent-1.
Board sum: 0
