Answer:
X=3,y=-4
Step-by-step explanation:
The only change is x so you could figure it out that way or do this:
4x=12 by subtracting the secound equation by the first one (since both y's are being multiplied by the same thing you can do this to cancel them out while making one equation). and than figure out x=3 from there you input that into eithger equation to figure out y. Hope this helped!
