how to solve 13 simultaneous equations in Excel Microsoft? watch

1. i have to solve an engineering question with involves finding values through solving 13 equations simultaneously

following are the simultaneous equations with atleast 2 unknows in each one that needs to be solved in excel

A*B = 0.46
B-C = 7
C-D = 0
D-E = 0
F/G = 0.000707
H/I = 0.00196
J/G = 29880.23952
K/I = 49880.3992
(1/L)-2*log(J*L) = 0.796
(1/M)-2*log(K*M) = 0.796
D/(G^2*L^2) = 42.474
E/(I^2*M^2) = 25.484
A-F-H = 0

how do i solve these equations simultaneously?

the detail of the question is given below in the attachment
