Could someone teach me how to do this question step by step i dont get it

Step-by-step explanation:

Written explanation:

You bring the y to the left side so it "matches" up with the bottom equation. Then you multiply -1 to the bottom or top (preferably the top) and add both equations. Then you solve like you normally would.

Visual explanation:

And then, you substitute y into one of the equations, find x, and wala! There might be more steps if you read the directions, but I am just explaining the actual part.

I hope that helps! If you have more questions (like Why did you do that? Where did you get that from?), don't hesitate to ask in the comments below. :)
