No. Here is a simple example where this is not the case:
x + y = 0
x + y = 1
If you subtract the first equation from the second, you get 0 = 1, which is clearly impossible. Graphically, you get two parallel lines, which never cross.
A system of linear equations that has at least one solution is called consistent.
The three quantities of solution for linear equations are consistent, inconsistent, and dependent. A consistent system has at least one solution, either unique or infinitely many. An inconsistent system has no solutions, meaning the equations represent parallel lines that never intersect. A dependent system has infinitely many solutions, indicating that the equations represent the same line in different forms.
A system of equations is a set of two or more equations that share common variables. The solutions to the system are the values of the variables that satisfy all equations simultaneously. Systems can be classified as consistent (having at least one solution) or inconsistent (having no solutions), and they can also be classified based on the number of solutions, such as having a unique solution or infinitely many solutions.
A consistent system with independent equations is one in which there is at least one solution, and the equations do not overlap in their constraints, meaning that no equation can be derived from another. In such a system, the equations represent different planes (or lines in two dimensions), and they intersect at one unique point (in the case of two variables) or along a line (for three variables). This unique intersection indicates that the system has a single solution that satisfies all equations simultaneously.
You don't need ANY factor. To find a unique solution, or a few, you would usually need to have as many equations as you have variables.

A system of equations is two or more equations that share at least one variable. Once you have determined your equations, solve for one of the variables and substitute in that solution to the other equation.

No.
The MATLAB backslash command () is used to efficiently solve linear systems of equations by performing matrix division. It calculates the solution to the system of equations by finding the least squares solution or the exact solution depending on the properties of the matrix. This command is particularly useful for solving large systems of linear equations in a fast and accurate manner.
When a linear system of equations equals zero, it typically means that the solution set consists of the trivial solution, where all variables are equal to zero, especially in homogeneous systems. This implies that the equations are consistent and have at least one solution. In some cases, if the system is dependent, there may be infinitely many solutions, but they will still satisfy the condition of equating to zero. Overall, the system describes a relationship among the variables that holds true under certain constraints.
A system of equations is considered consistent if it has at least one solution, and it is coincident if all solutions are the same line (infinitely many solutions). If the system has no solutions, it is inconsistent. To determine the nature of a specific system, you need to analyze its equations; for example, if two equations represent the same line, it is consistent and coincident, while parallel lines indicate inconsistency.
A consistent system refers to a set of equations or conditions that do not contradict each other, meaning there is at least one solution that satisfies all equations simultaneously. In mathematics, particularly in linear algebra, a consistent system can be classified as either having a unique solution or infinitely many solutions. This contrasts with an inconsistent system, where no solutions exist due to conflicting equations. Consistency is crucial for ensuring that mathematical models accurately represent real-world scenarios.
