- An inconsistent equation results when the variables cancel out and a false statement remains. $ax + b = c$ is an inconsistent equation if $a = 0$ and $b neq c$. Graphically, an inconsistent equation represents parallel lines that never intersect.

The equations in a two variable system of equations are linear and hence can be thought of as equations of two lines. When these two lines are parallel, then the system has infinitely many solutions. When two lines are parallel, their equations can usually be expressed as multiples of each other and that’s usually a quick way to spot systems with i...
There also exist two variable system of equations with no solution at all. This happens when as we attempt to solve the system we end up an equation that makes no sense mathematically. For example, solve the system of equations below: Using matrix method we can solve the above as follows: Reducing the above to Row Echelon form can be done as follow...
When discussing the different methods of solving systems of equations, we only looked at examples of systems with one unique solution set. These are known as Consistent systems of equations but they are not the only ones. Three variable systems of equations with infinitely many solution sets are also called consistent. Since the equations in a thre...
Three variable systems of equations with no solution arise when the planed formed by the equations in the system neither meet at point nor are they parallel. As a result, when solving these systems, we end up with equations that make no mathematical sense. For example; solve the system of equations below Solution: Using Matrix method: In the last r...
Algebraically, for such a case, a 1 /a 2 = b 1 /b 2 ≠ c 1 /c 2, and the pair of linear equations in two variables is said to be inconsistent. As shown in the graph above, the pair of lines a 1 x +b 1 y +c 1 =0 and a 2 x +b 2 y +c 1 =0 are parallel to each other. Therefore, there exists no solution for such a pair.

Inconsistent Equation. An equation that has no solution is called an inconsistent equation. The solution set to an inconsistent equation has no members. The set with no mem-bers is called the empty set and it is denoted by the symbol .
Textbook Question. The equations in Exercises 79–90 combine the types of equations we have discussed in this section. Solve each equation. Then state whether the equation is an identity, a conditional equation, or an inconsistent equation. 4/ (x^2 + 3x - 10) - 1/ (x^2 + x - 6) = 3/ (x^2 - x - 12) 214.
Definition. An inconsistent equation is a linear equation with no solution. It represents lines that are parallel and never intersect.
Feb 24, 2012 · inconsistent system: A system with no solutions is called an inconsistent system. For linear equations, this occurs with parallel lines. substitute: In algebra, to substitute means to replace a variable or term with a specific value.
