I have never seen the term 'symbolic' used in this way. There are 4 methods used to solve a system of linear equations in two variables.
Graphing, Substitution, Elimination, and Cramer's Rule.
Elimination and substitution are two methods.
They are the simplest form of relationship between two variables. Non-linear equations are often converted - by transforming variables - to linear equations.
It means that there is no set of values for the variables such that all the linear equations are simultaneously true.

There are more than two methods, and of these, matrix inversion is probably the easiest for solving systems of linear equations in several unknowns.

A system of linear equations is two or more simultaneous linear equations. In mathematics, a system of linear equations (or linear system) is a collection of linear equations involving the same set of variables.
A system of linear equations.
a system of equations
Simultaneous equations have at least two unknown variables.
The solution of a system of linear equations is a pair of values that make both of the equations true.
It means that there is no set of values for the variables such that all the linear equations are simultaneously true.
