Find a solution -5x+y=-5 -4x+2y=2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-5x + y = -5,    (1)    
-4x + 2y = 2.    (2)

Apply the Substitution method. 

From (1), express y = -5 + 5x and substitute it into equation (2). You will get a single equation for x

-4x + 2*(-5 + 5x) = 2.   (3)

Now simplify and solve it:

-4x -10 + 10x = 2,

6x = 2 + 10,
6x = 12.

x =  = 2.

So, you just found the solution x = 2.

Do you know what to do next?  How would you find "y"?
