一道英文数学题

前提条件：team x scored p points more than team y, and the two teams togther scored a total of 10 points

试比较【twice the number of points team y scored】和【10-p】的大小

Answer 1

楼主要求的，可能是用英语答这道题。所以特别将一楼提供的解法转成英语，如下：

Let
X denote the number of points scored by team x; and
Y denote the number of points scored by team y.

It is given that
X-Y=P and
X+Y=10

Hence,
(X+Y) - (X-Y) = (10) - (P)
<=> 2Y = 10-P

Therefore, twice the number of points team y scored (i.e. 2Y) is equal to (10 - p).

Answer 2

译文：【前提条件： X 队比Y 队多P分，X与Y队的总和是10分
试比较 【Y队分数的2倍（即2Y）】和 【10-p】的大小
回答：X-Y=P X+Y=10 则（X+Y）—（X-Y）=（10）—（P） 即为2Y=10-P
两者相等
