An urgent solution to a math problem in Quanzhou senior high school entrance examination
Students, I won't say the first question.

Solution: obtained by (1), AP/AC=AE/AB=DE/BC.

That is x/8=AE/ 10=DE/6.

AE=5x/4 PE=3x/4。

And the perimeter of the quadrilateral PECB is y, that is

PE+EC+CB+BP=y

Then 3x/4+(8-5x/4)+6+(10-x) = y.

Simplify and acquire

y=24-3x/2

Ok, the image is a straight line. If you stop asking me,
