question: The figure shows three parallel horizontal lines, with a diagonal line running through them on the left and a vertical line on the right. The diagonal line on the left intersects with three horizontal lines, with a length of 2x+6 for the lower section and 20-5x for the upper section. The vertical line on the right intersects with three horizontal lines, with a length of y for the upper section and 3/5y+2 for the lower section. The two short line segments cut by the left line are of equal length, and the two short line segments cut by the right line are of equal lengthFind y.
  Choices:
  A:3
  B:4.5
  C:5
  D:6
