Geez thats a hard one...I'm trying to find whole numbers but I cant. I only came up with one...
I havent done this in awhile, so let me know I fi messed something up erin.
5x - 3y = 15
5(6) - 3y = 15
30 - 3y = 15
-3y = -15
y = 5 therefore, (6,5) is the answer
and so forth...Do that picking a random number for x and solve. Get it?
