Answer:
Explanation:
Your first step is to figure out which variable you want to cancel out.
Luckily, all these problems have x or y already set up to eliminate.
You can find these variables because they are opposite signs of each other, such as -x and x
Add the y's together and the #'s on the other side together, then solve to find the 2nd variable. Once you find one, you can plug that answer into the easier of the two equations and solve for the other variable.
