how do i solve x+3y=56

  • math -

    There is an infinite number of solutions to x+3y=56.

    Do you particularly favor any one solution?

  • math -

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