X + 1/4x = 15
4/4x + 1/4x = 15
5/4x = 15
5x = 60
x = 12
Answer: 
============================================
Work Shown:

---------------
Explanation:
The idea is to first get all the y terms to one side. I did this by subtracting 2y from both sides in the third step.
Then factor out y and divide both sides by (8x-2)
Afterward there's the optional steps of simplifying (as shown in the final two steps).
Answer:
My answer is D) y = 2(x - 2.5)^2 + 6

2x² + 3x + 1
2x² + 2x + x + 1
(2x + 1)(x + 1)
