solving xy+ax+by=c

How would you obtain the solutions to the equation xy+7x+3y=70? The values of x and y should be integers.

http://www.alpertron.com.ar/METHODS.HTM#SHyperb has step-by-step instructions and http://www.alpertron.com.ar/QUAD.HTM is a solver. There are only two solutions with x and y nonnegative, with six others if you allow negatives.
