There is an infinite number of answers to this equation. If you have TWO variables ('x' and 'y') you need TWO equations to find a unique x,y which solves the equations.
You CAN graph this equation......the graph will display all of the values that solve the equation,
First put the equation into f(x) = y =
x=2/3y+6 2/3 y = 6-x then y = f(x) = 3/2 (6) - 3/2x = 9-3/2x so plug that into the graph function of the calculator to see all of the x,y values that 'solve ' this equation ! (it is an infinite nearly vertical line....you see it?)
