Hi,

Please, how can I isolate "d" variable in this equation? Which the value of "d"?

If I didn't wrong anything, the equation will be like this, but, how to find the value of "d"?

You have a quartic in , which often is impractical to solve in closed form when you have symbolic coefficients, but look here.

CaptainBlack,

Thank you for your answer and your tip. After several attempts I verified that would not be practical to solve this system. (Doh)

Thank you,
