## Solving Systems of Equations with Three Variables

There are three ways to solve a system of equations with 3 variables. One is substitution, which is solving one of the equations for a variable, and then plugging that into

## How to Solve Systems by Substitution With 3 Variables : Algebra

Multiplying both sides by negative 1, you get z is equal to negative 4. So we're done. Let's verify that these solutions, or the solution of x is negative 1, y is equal to 2, z is equal to negative 4, actually satisfies
