Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Find the solutions to the linear equations represented by the models shown, where circles and squares are shown evenly balanced on balance
beams. Assume the welght of a circle is 1 unit and the weight of a square is x units,
x = 9
x=2
x = 6
x=5
X= 4
x=3​

Answer 1

• x=3
• x=6
• x=9

Explanation:

Match the circles on the left with circles on the right. Divide any remaining circles evenly between the remaining squares. See below for one way to do this.
