The equation which relates the change in price per sticker purchased is y = 2.05x
- The number of stickers purchased = 10
The change in price per sticker purchased can be expressed as :
- Price change / number of stickers
- Change in price per sticker = $20.50 / 10
- Change in price per sticker purchased = 2.05
Therefore, the required equation which related y and x is :
y = 2.05x

Since both equations are equal to y you can just make them equal to each other, like this 3x + 7 = x - 9. From there isolate the varible x on one side so that the solution will be on the other side of the equation. I'll do the steps too for you.
3x + 7 = x - 9
2x + 7 = -9
2x = -16
x = -8
Hope this helps :)
