    how do you find solutions to an equation like this (6-2x-2y=0)?

    You can write it in a way so that one variable is dependent on the other:

    [tex] y = \frac{-6 + 2x}{-2} [/tex]


    [tex] x = \frac{-6+2y}{-2} [/tex]

    So for the first one you have a function, [itex] f(x) [/itex] that for every [itex] f(x=value) [/itex] you have a solution.

    The solution set to that equation is a line, namely y=3-x.
