Using Lagrangian to find the maxima for a multivariable function solve block wont find a solution.

Using Lagrangian to find the maxima for a multivariable function, solve block wont find a solution, I'm using the solve block to try and solve the functions given by the gradient of the Lagrangian.

The solve block give error: No solution was found. Trying changing the guess value

Any help is appreciated

Hi,

It seems there is a mix up of equals between:-

assignment equals [shift]: shown as a colon plus equal sign

comparison equals [ctrl]= shown as a bold equal sign.

Solve blocks are sensitive to values used as guesses so trial and error is often necessary.

Here is one solution after changing some comparison equals to assignment equals to define functions.
