x=3

Explanation:

The method of figuring out this problem lies in the substitution of 0 for y. What does being on the x-axis mean? It means that the point which crosses it is in the form (x,0), where 0 will remain constant for all points on the x-axis. So, that means that when y=0, we can solve for x to find out the x-coordinate of the point in which 2x+y=6.
#2x+y=6#
#2x+(0)=6#
#2x=6#
#x=3#
Thus, when y is 0, x is 3, giving us the point (3,0) for when the line crosses the x-axis
