Solve:
-2x + 5y = -1
4x - 2y = -6

(-2, -1)

Step-by-step explanation:

Let's eliminate x using addition / subtraction.  Multiply the entire first equation by 2, obtaining the following result:

-4x + 10y = -2

4x  - 2y  = -6

         8y = -8, and so y = -1.  

Substituting -1 for y in the 2nd equation, we get:

         4x - 2(-1) = -6, or

          4x + 2 = -6, or

          4x = -8, and so x = -2.

The solution to this system is (-2, -1).
