C=1*L-(2*L+3);
C=7/(4*5*L^6);
Both C and L are unknown variables. How could I solve these equations? Looking for your answer!

Sounds like homework - is it? I'd set them equal to each other (to eliminate C) then use fzero() to find L, then stick in either equation to find C. Give that a try and come back with MATLAB code if you want any help with it. By the way, I don't see how the quadratic equation applies to this 6th order equation.

Eliminate C and get the polynomial equation
20*L^7 + 60*L^6 + 7 = 0 (<-- Corrected)
and use 'roots'.
