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"? Thanks in advance. Euler

Euler You have a quartic in $\displaystyle d$ , which often is impractical to solve in closed form when you have symbolic coefficients, but look here. CB
CaptainBlack, Thank you for your answer and your tip. After several attempts I verified that would not be practical to solve this system. Thank you, Euler
