We have three methods.
1) Cramer's rule method (Or) Determinant method
2) Rank method
3) Matrix Inversion method.

My own question: For just 2 unknowns, do any of the above include the "ordinary" way in which you multiply one or the equations through so one of the unknowns match in both lines, subtract, solve the now-single difference for its unknown then substitute back? Or do the above only apply if you're solving great banks of equations simultaneously.
It's the only method I know but I recall being taught how to stretch it to 3 unknowns, but it becomes rather long-winded.
I ask out of curiosity because I "learnt" matrices without understanding them and with only the haziest hint that they have any uses!
By the substitution method By the elimination method By plotting them on a graph
The analytical method involves simultaneous equations but if you do not know that, draw graphs of the equations: with one variable represented per axis. The solution, if any, is where the graphs meet.
Solve the following systems of simultaneous linear equations using Gauss elimination method and Gauss-Seidel Method 2x1+3x2+7x3 = 12 -----(1) x1-4x2+5x3 = 2 -----(2) 4x1+5x2-12x3= -3 ----(3) Answer: I'm not here to answer your university/college assignment questions. Please refer to the related question below and use the algorithm, which you should have in your notes anyway, to do the work yourself.
Without any equality signs the given terms can't be considered to be simultaneous equations.
it works exactly the same as it does with linear equations, you don't need to do any differentiation or anything fancy with this method, just have to plug in values of x, so it shouldn't make a difference if the equation is linear or nonlinear.
By the substitution method By the elimination method By plotting them on a graph
Simultaneous equations can be solved using the elimination method.

The elimination method and the substitutionmethod.
Equations = the method
Without any equality signs the given terms are not simultaneous equations and so therefore no solutions are possible.
Higher-level mathematical concepts, such as entirely new methods of calculation, may be patented. For example, this is the abstract of a patent application being reviewed at the moment: A method for obtaining an estimate of a solution to a first system of linear equations. The method comprises obtaining a second system of linear equations, obtaining an estimate of a solution to said second system of linear equations, determining differences between said first and second systems of linear equations, and determining an estimate of a solution to said first system of linear equations based upon said differences and said estimate of said solution to said second system of linear equations. In the language of the various laws, this would be called a "process," which the statute degines as "a process, act, or method." Also according to the law, the process must be useful and novel. It's worth noting, though, that case law has defined that "laws of nature, physical phenomena, and abstract ideas are not patentable subject matter."
There are no disadvantages. There are three main ways to solve linear equations which are: substitution, graphing, and elimination. The method that is most appropriate can be found by looking at the equation.
