Solve each system of equations. If the system has no solution, say that it is inconsistent. For Problems 19-30, graph the lines of the system.
$$
\left\{\begin{array}{r}
2 x-2 y+3 z=6 \\
4 x-3 y+2 z=0 \\
-2 x+3 y-7 z=1
\end{array}\right.

Key Concepts

System of Linear Equations

A system of linear equations consists of two or more linear equations with common variables. The goal is to find a set of values for these variables that simultaneously satisfies all the equations in the system. This concept is fundamental in algebra and is widely used to model and solve real-world problems where multiple conditions must be met at once.

Gaussian Elimination

Gaussian elimination is a systematic method for solving systems of linear equations. It involves using row operations on the augmented matrix of the system to reduce it to an upper triangular (or row-echelon) form, from which the solutions can be found by back-substitution. This method provides a clear procedure for determining whether the system has a unique solution, infinitely many solutions, or no solution at all.

Graphical Representation of Linear Equations

Graphing linear equations is a visual approach to understanding and solving systems of equations. Each equation in a two-variable system can be represented as a line in the plane, and the solution to the system corresponds to the point or points where the lines intersect. Graphical methods help in visualizing the nature of solutions, including cases where there is no intersection (indicating an inconsistent system) or infinitely many intersections (indicating dependent equations).

Inconsistent Systems

An inconsistent system is one in which the equations do not have any common solution, meaning that no set of variable values can satisfy all the equations simultaneously. In the context of linear systems, inconsistency is often revealed during the elimination process when an equation reduces to a false statement, such as 0 = 1, indicating that the lines (or planes in higher dimensions) do not all intersect at a common point.
