So eight. Why is 15 minus four x and X plus two wise for So let's right here. X as four minus two y and plug X into the above equation here. So for equation one. So we have eight y is equal to 15 minus four into four, minus two y. So wait. My eight. Why is 15 minus 16 plus eight y So, Hey, why is 15 minus 16 plus eight? Y Well, it looks here. If we subtract eight y on both sides, we'll get zero. Why is negative? One? Ah, zero is negative. One Dad does not make sense. So we have no solution here.
