Identify a Consistent System of Three Linear Equations with Dependent Equations
When solving a system of three linear equations, if the process results in an equation with no variables and a true statement (such as ), it indicates that the system has infinitely many solutions. Such a system is consistent with dependent equations, and its solution will show how two of the variables depend on the third.
