Answer:
(-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).
