Answer:

The solution is (2, 10)

Step-by-step explanation:

In order to solve this system of equations, multiply the second equation by 2, then add through. This will allow the x terms to cancel.

10x + 3y = 50

-10x - 2y = -40

---------------------

y = 10

Now that we have y, plug in and find x.

-5x - y = -20

-5x - 10 = -20

-5x = -10

x = 2
