C. exactly two
D. infinitely many

Answer 1

@swissgirl

Answer 2

B

Answer 3

You are given that \(\large\color{blue}{ -x + 2y }\) is equivalent to \(\large\color{blue}{ 6 }\) (based on equation 1), And you are given that \(\large\color{blue}{ -x + 2y }\) is equivalent to \(\large\color{blue}{ 0 }\) (based on equation 2).

if one number is equal to \(\large\color{blue}{ 6 }\) and to \(\large\color{blue}{ 0}\) (at the same time), is there such a number ?

Answer 4

(if you have nay questions, ask)

Answer 5

Ok, thanks :D how did you find it?? @rileyreid1998

Answer 6

would that mean that there are none?

Answer 7

Answer 8

@SolomonZelman

Answer 9

are you sure there are infinity of numbers that are equivalent to 6 and to 0 (at the same time) ?

Answer 10

yes.

Answer 11

there is no number that is equivalent to 0 and to 6 at once.

Answer 12

(You can say it is \(\large\color{slate}{\displaystyle \int 0~~dx}\) jk)

Answer 13

Is that the same thing as none? I said A. none.

Answer 14

so its A?

Answer 15

What I said at last with that was a joke, it was in parenthesis.
