Question 342986
Here's the basic outline to solving this problem


1) Select an equation and complete the squares for both x and y. You've already done that. Call this equation 3.


2) Select a variable to solve for in equation 3. Let's say you choose to solve for 'y'. 


3) Once you've solved for 'y', plug that solved expression into each 'y' of the other equation. Once you've done this, every 'y' will essentially be replaced by 'x' terms and you'll have an equation with only one variable.


4) Expand, combine like terms, and simplify to get the equation with one variable in the form {{{ax^2+bx+c=0}}}. 


5) Now use the quadratic formula to solve for 'x'.


6) Use the solution(s) found in step 5) to find the corresponding solution(s) in terms of 'y'.
