You then know that \[x + y = 750.\] At $65\%$ efficiency the first generator produces $0.65 \times x$ MW of power. How much power does the second generator produce at $75\%$ efficiency? The sum of thee is 530 MW. This give you a second equation in $x$ and $y.$ Solve the equations for $x$ and $y.$ Make sure you verify your answer. Harley
