Equation Sort

  1. Sort the equations into three groups:

    Equations with only one solution

    Equations with many solutions

    Equations with no solutions

  2. Explain how you know where the equation should be placed.

  3. Take one of the equations and change it so that it has a different number of solutions.

Equations:

2x + 5 = 16

6(x + 1) = 6x + 6

3(x + 4) = 3x + 4

2x + 3x = 2x + 12

x + 5 = 5 + x

5 + 4x = 15

2x + 8 = 2x + 3

2x + 7 = 2x + x

3x + 8 = 20

3x – 6 = 6 – 3x

x + 3 = 6 + x

x + 2 + x + 1 = 2x + 3
