In this lesson you will study an algebraic method
for solving linear system of three equations and
three variables. This method is often referred
to as the Elimination Method.
2
Choose a variable and eliminate it by combining
two equations.
3
Select a DIFFERENT combination that will
eliminate the SAME variable.
Equation 1
Twice Equation 2

Solve the new system for the remaining variables
using either linear combination or the
substitution method.
