Turn both examples to Slope intercept form (Y=MX+B) Make the questions where one part, X or Y cancel each other out. Then, with Y=X/Y+b, solve the equation to get X/Y. Let's say you found X. Substitute that number for the X in the other equation and solve to get the Y. And there you have it, your coordinates
