Answer: x=5

Step-by-step explanation:

Assuming that you are using the variable "y" in the space (meaning I took your equation to be -2x+y=-12), you used the value of -2. This gives you -2x-2=-12. Wait! We can add -2 to both sides, which gives us -2x=-10. We can then divide -2 from both sides, which makes x stand alone, and the other side to be 5. Therefore x=5.

Remember that I am writing this solution assuming that you are using the variable "y" in the blank space with a co-efficient of 1.

I hope this helps. If my understanding is wrong, then comment below and I will give you the correct answer in no time :)

Answer:

A) Categorical

B) Nominal

Step-by-step explanation:

 As we can see from the data that the question only had two answers i-e Yes or no so therefore they were categorical rather than quantitative in which he would have asked the user for how much money they were willing to pay more.

It's nominal because he asked in terms of more or less rather than some specific number
