Hello everyone.
I tried to solve the equation with several solutions.
Probably the solution given by Mathcad 15 is correct.
However, the Prime7 method of entering equations in a matrix does not give a solution, and the Solve Block method gives a numeric value, which is probably incorrect.
I attached these files.
Please advise.
Solved! Go to Solution.

hank you for your reply.
I have mistake in Vave(D) .
Solve block in Prime7 is no problem.
