Answer:
0
Step-by-step explanation:
1. Distribute: 6x-12 - 6x+12
2. Combine like terms: 0
Answer:
0
Step-by-step explanation:
First you want to do distributive properties, so multiply 2 and -4 by 3. leaving you with 6x-12-6x+12. then we have to combine all the like terms. so you can either add 6x to the negative 6x or take away 6x from the positive 6x. Same with the 12's. so once you've combined all the like terms you should be left with 0. Thus, your answer would be 0.
