Sure, let's solve this system of equations step by step.## Step 1: Rewrite the equationsFirst, let's rewrite the equations for clarity:1. `0.6 * x^-0.4 * y^0.4 - 50λ = 0`2. `0.4 * x^0.6 * y^-0.6 - 20λ = 0`3. `200 - 50x - 20y = 0`## Step 2: Solve for λ in the first two equationsFrom equation 1, we can solve for λ:```0.6 * x^-0.4 * y^0.4 = 50λλ = (0.6 * x^-0.4 * y^0.4) / 50```Similarly, from equation 2:```0.4 * x^0.6 * y^-0.6 = 20λλ = (0.4 * x^0.6 * y^-0.6) / 20```## Step 3: Set the two λ equations equal to each otherNow, we can set the two λ equations equal to each other and solve for x:```(0.6 * x^-0.4 * y^0.4) / 50 = (0.4 * x^0.6 * y^-0.6) / 20```## Step 4: Solve for xSolving the above equation for x, we get:```x = ((0.6 * y^0.4) / (0.4 * y^-0.6))^(1/1.0)```## Step 5: Substitute x into the third equationSubstitute x into the third equation and solve for y:```200 - 50 * ((0.6 * y^0.4) / (0.4 * y^-0.6))^(1/1.0) - 20y = 0```Solving this equation will give you the value of y.## Step 6: Substitute y into the equation for xFinally, substitute the value of y into the equation for x to get the value of x.Please note that the actual calculations might be complex and require the use of a calculator or a software tool.
