Dear All Recently i'm involving in solving 4 simultaneous equations by help of MATLAB and already i attached a file which consists of the equations

previously i used fsolve in order to get the answers , however because of the initial guess which is required for function fsolve i could't find solid answers. and even i'm not sure that using fsolve function was a reasonable choice or not .

Please help me in this regards. Thanks in Advance .

To solve a system of equations you must have at least the same number of equations as you have unknown quantities. I'm guessing that the unknowns you need to solve for are the red ones on the bottom. Are you trying to obtain a symbolic solution, or do you have numeric values which can be used to obtain a numeric solution?

Thank you for your attention . Except those red variables on the bottom , others are known and i'm trying to obtain numerical solution for those red ones .
