Answer 2

Answer:

Step-by-step explanation:

There can be an infinite number of equations that equals 18.

Let us try this as a straight line in a coordinate plane

x+y =18

This solution will be all the points on the line whose x and y coordinates add up to 18

Example:

(1,17)(2,16)(0,18)(-1,19) and so on.  i.e. all the points on the line.
