Proof by contradiction is a form of proof that establishes the truth or the validity of a proposition, by showing that assuming the proposition to be false leads to a contradiction. I googled this so it may not be correct
4x-6= x+6
4x= x + 12
5x= 12
X= 12/5
X= 2.5
Answer:
- 1 < x < 4
Step-by-step explanation:
