Directions: In each category, choose ALL that apply.

1. Choose the equations that are ALWAYS TRUE!
Check ALL that apply and hit Submit.
1. 2x + 1 = 3x + 6

2. a + 3 = 3 + a

3. c + 6 = c

4. 2(x + 3) = 4(x - 6)

5. 8(x + 1) = 8x + 8

6. x + x + x = 3x

7. a + 1 = a - 1

2. Choose the equations that are ALWAYS FALSE!
Check ALL that apply and hit Submit.
1. 3 + (4 + c) = 7 + c

2. 3 + x = x

3. 7x + 3 = 10

4. b - 0.5 = b

5. 3(a + 1) = 3a

6. 3x - 4 = 4 - 3x

7. 4x + 5x = 16 - x


3. Choose the equations whose truth depends upon the value substituted into the equation!
Check ALL that apply and hit Submit.
1. 5x = x + x + x

2. 0.1 + c = c

3. 4(a - 1) = 12

4. 3 + x - 4 = x - 1

5. 2x + 3x = 24 - x

6. a + 6 = 2a + 6

7. 3a + 1 = 1 + 3a
