You can put this solution on YOUR website!
36+=+4x+%2B+2y
18-2x+=+y
so graph that
graph+%28300%2C+200%2C+-5%2C+15%2C+-5%2C+25%2C+18-2x%29
So there are many answers. Anywhere on the line between y=18 and x = 9 that are integers values for x and y work
x = 0, y = 18
x = 1, y = 16
x = 2, y = 14 etc etc
all the way to x=9, y = 0
