The system of equations to solve is given as:

In order to solve this system of linear equations, we use substitution method.
In substitution method, we substitute the value of any one variable in the other equation.
So, we substitute the value of 'y' from first equation in the second equation.
This gives,

Dividing both sides by 3, we get:

Now, 
Therefore, the solution is (-2, -4)
