I have tried to searched for functions online and apply it, but still it does not work well.

May I ask how can I solve symbolic simultaneous equations with Matlab? Or is there anything went wrong with my program?

Consider a stepped beam shown in below. The beam is statically indeterminate and a concentrated force P is applied at B. As shown in the figure, the segments of AC and CD have the rigidities of EI1 and EI2, respectively. Determine the deflections at B and C using singularity functions. Note: You might need to use a symbolic equation solver (Matlab, Mathematica, etc.) to solve simultaneous equations.

(below, in my attempt)

(I use symbol

Where F(A) should not be in terms of F(A) itself. A, B, D, M suppose all can be expressed in constants (i.e. P L E I1 I2).

By what command can I solve the deflection function (y1 and y2) only in terms of constants (i.e. P L E I1 I2)? Or if my calculation is incorrect? Thank you.
