Methods for Solving Systems of Equations with 3 Variables

1. Substitution Method

This method involves isolating one variable in one equation and substituting that expression into another equation, effectively reducing the system to two variables.

2. Elimination Method

By adding or subtracting equations strategically, we can eliminate one variable, creating a new system with two variables.

3. Matrix Method

This method involves representing the system as an augmented matrix and performing row operations to transform it into a row echelon form. The resulting matrix provides the solutions to the system.

Applications of Systems of Equations with 3 Variables

Systems of equations with three variables find far-reaching applications in diverse fields:
