How can I solve this two shaded equations for d1 and d2?

This is the student version and I am a begginer user

Is c known? As far as I can see, c has never been defined. Personally, I think c is 42, which we have been told by another welll known source to be the answer to all of the important questions. In fact, I have heard in the next version of MATLAB, they have plans to replace all undefined variables with the number 42. Hey. It might be the correct number after all.

But don't tell anyone I said this, as I might be leaking valuable product information to the world. It is a secret!

yes, c is known; 0.15 to be exact.

syms d1 d2 Grin
eq = [d2 == Grin * d1; (d1+d2) / 2 == 0.15];
sol = solve(eq,[d1,d2]);
sol_d1 = sol.d1
sol_d2 = sol.d2
