Do you particularly favor any one solution?

**MathMate**, Wednesday, July 29, 2009 at 2:13pmSince this is a single equation containing two unknowns (x and y), it is not possible to have an explicit solution for x and y.

The given equation expresses the relationship between x and y, namely if one is known , we can find the value of the other.

The relationship can also be expressed as a straight line graph, or by expressing the equation differently:

x+3y=56, or

x=56-3y, or

y=(56-x)/3

The set of possible solution to the equation is called the solution set, which might contain:

{(2,18), (5,17), (8,16), ...}
