Without a second set of equations, you can't solve for either X or Y.
That equation alone would, however, be the graph of a line. If you rearrange the equation to y=-9/5x+(4567/5) by subtracting 9x from each side and dividing by 5, you can see it would be a line with a slope of -9/5 and an intercept of 4567/5, or 913.4.
