how do i solve x+3y=56

bobpursley,
There is an infinite number of solutions to x+3y=56.
Do you particularly favor any one solution?

MathMate,
Since 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=563y, or
y=(56x)/3
The set of possible solution to the equation is called the solution set, which might contain:
{(2,18), (5,17), (8,16), ...}
