There are 3 available methods - Substitution , Elimination and Matrix.

The substitution method is used to eliminate one of the variables by replacement.

The elimination method is used for solving linear systems.

A Matrix is an array of numbers.

Lets use Substitution to solve this system.

$x+3y=0$

$x=-3y


$

Substitute $x=-3y$ into $2x+6y=12$ 

 $2x+6y=12$

$2*-3y+6y=12$

$0=12$
