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
