Question

Match each item in Column A to an answer in Column B.





What is the best way to classify each equation?


Column A Column B

1. 8x +24=2(4x+12) a. identity
2. 5x +18-x=2(2x+8) b. contradiction
3. 7(3x-2)=20x-13 c. niether
4. 3x+2(x-10)=5(x-4)

Answer 1

plz help

Answer 2

Solve them. There are three possible outcomes.

Something obvious, like 4 = 4. That's an identity.
Something horrible, like 3 = 7. That's a contradiction.
Something conditional, like x = 12. That's neither.

Go!
