Description: Solve each system using the elimination method. If a system is inconsistent or has dependent equations, say so. -2 x+3 y =-16 2 x-5 y =24

step 1 We're going to solve the system using the elimination method. So as you can see, we have a posit

Key Concepts

Dependent Equations

Dependent equations occur when one equation in a system is simply a multiple of another, leading to infinitely many solutions. In these cases, the equations represent the same line graphically, meaning every solution of one equation is also a solution of the other. Detecting dependency is essential to correctly classify the nature of the solutions of a system.

System of Linear Equations

A system of linear equations consists of two or more equations with the same set of variables. The goal is to find values for the variables that satisfy all equations simultaneously. Such systems can have a unique solution, infinitely many solutions (if the equations are dependent), or no solution (if the equations are inconsistent).

Elimination Method

The elimination method is a technique used to solve systems of linear equations by strategically adding or subtracting equations to cancel out one of the variables. This reduces the system to a single equation with one variable, which can then be solved easily. Once one variable is determined, its value is substituted back into one of the original equations to find the other variable.

Consistent and Inconsistent Systems

A consistent system of equations is one that has at least one solution, meaning there is a set of values that satisfies all the equations. An inconsistent system, on the other hand, has no solution because the equations contradict each other, often indicated by a false statement resulting after elimination or substitution.
