Before I mention the problems with your equations (4) and (5), let me first suggest to you that your equations are pure numbers. You consistently fail to mention the units in which the variables are measured. As a matter of fact, the question of the unit of measure is the crux of the transformation problem. So if you don't have the problem of unit upper most in your mind, you cannot even begin to understand the nature of the problem, let alone solving it. Now, my sense is that you would say, the numbers are given in money terms. Now, your world of equations have three commodities. It appears that the first one is something like iron, second one is something like wheat, and the third one could be gold. So let us say, gold is the money commodity in your world, so the values/prices of x and y are given in terms of gold. In that case, your third equation turns out to be 50x + 90y + r(50x + 90y) = 200 (3'). Now, the system of equations (1), (2), and (3') are in well defined units, and they solve for x, y, and r. Given your unnecessary simple reproduction constraint on the system, it must follow that: r(225x+90y)+r(100x+120y)+r(50x+90y) = 200. But this is nothing but one of Bortkiewicz's solution in which the gold sector is taken as the luxury/money commodity sector with simple reproduction constraint on the system. Here by design, total surplus value will always be equal to total profits. And if the gold sector is made of average organic composition of capital, then total value will also be equal to total surplus value. This is just one of those special cases. All this should have already made it clear that your equations (4) and (5) must be at best redundant. But actually they are worse than that. Mathematically, your r has to be either known or unknown, they cannot be both at the same time. In equation (4), on the right hand side you have r as an unknown variable, whereas the left hand side 875 is derived by taking r = 8/27. So this is simply illegitimate. Same with equation (5). Whether you like it or not, you have presented a simultaneous equation system with three unknowns and five equations. If all your five equations are independent ones, then your system is overdetermined (try solving for x, y, and r from your five equations, which you haven't done yet). In a system with unique solution, the two equations should be derivable from the first three equations. On a general note: I would advise that a solution to the transformation problem does not lay in being cute by somehow showing that the two invariance conditions satisfy. One needs to first think about what is the nature of the problem, before trying to come up with a quantitative solutions.
