x, tables for 5
y, tables for 8

system%28x%2By%3C12%2C5x%2B8y=79%29

system%28y%3C-x%2B12%2Cy=-%285%2F8%29x%2B79%2F5%29

Looking just at the EQUATIONS
graph%28300%2C300%2C-1%2C12%2C-1%2C12%2C-x%2B12%2C-%285%2F8%29x%2B79%2F8%29
Reading integer or whole numbered points can be easier if done on actual grid or real graph paper. Any solutions will be to the left of the intersection point.
