What advantages does the method of substitution have over graphing for solving systems of​ equations

A.
When using the graphing​ method, if either coordinate in the solution is a​ fraction, guessing the values may be required. Substitution requires no guessing.
B.
It is easier to solve application problems with substitution than with graphing.
C.
Graphing cannot be used to solve dependent or inconsistent systems due to the nature of the lines involved. Substitution can solve these.
D.
Since both methods are capable of solving a​ system, substitution has no advantages over graphing.?

C. Graphing cannot be used to solve dependent or inconsistent systems due to the nature of the lines involved. Substitution can solve these.
