Solve for asset classes calculator, regarding, function, practice, specific

Hi,

during the several practice exams I saw several issues regarding solving for asset class weight. I.e. some corner portfolios are given and you have to solve for the optimal weights to get a specific return.

This works in the formula overall return = Return of portfolio 1 w + return portfolio 2 (1-w)

How can I quickly solve for the weight. I tried a trial and error process so for. Is there also a function on the calculator?

Thank you in advance for a feedback
