   How many solutions does a linear system of equations have?

   • With linear systems of equations, there are three possible outcomes in terms of number of solutions: One solution. Infinitely many solutions. No Solutions at all. If there is one solution, it means that there is a single intersection between the two lines that your equations give. For example, considering the following equations:

   Do all linear equations have exactly one solution?

   • So far, whenever we have solved a system of linear equations, we have always found exactly one solution. This is not always the case; we will find in this section that some systems do not have a solution, and others have more than one. We start with a very simple example. Consider the following linear system: x − y = 0. x − y = 0.

   Does a linear system have a solution?

   • The system has no solution. For a system involving two variables (x and y), each linear equation determines a line on the xy - plane. Because a solution to a linear system must satisfy all of the equations, the solution set is the intersection of these lines, and is hence either a line, a single point, or the empty set.

   How do you find the number of solutions of a linear equation?

   • A linear equation in two variables is an equation of the form ax + by + c = 0 where a, b, c ∈ R, a, and b ≠ 0. When we consider a system of linear equations, we can find the number of solutions by comparing the coefficients of the variables of the equations. Also, we can find the number of solutions by the graphical method.

   How do you solve a system of linear equations?

   • There are several algorithms for solving a system of linear equations. When the solution set is finite, it is reduced to a single element. In this case, the unique solution is described by a sequence of equations whose left-hand sides are the names of the unknowns and right-hand sides are the corresponding values, for example .

   A solution to a linear system is an assignment of values to the variables such that all the equations are simultaneously satisfied. In the example above, a solution is given by the ordered triple since it makes all three equations valid. Linear systems are a fundamental part of linear algebra, a subject used in most modern mathematics.
