最简单的就是用数字去凑 1.2.3都可以凑出来 第一种 x=100 y=5 z=1 第二种x=1/6 y=1/5 z=1/4 第三种 x=100 y=1/5 z=1/4 谢谢
(xy+xz)-(xy+z)=xz-z=z(x-1),z(x-1)为奇数，z和x-1都为奇数，x为偶数，条件1）充分 ...
x=12u=4(2y+3),=> Y=3/2(u-1),X=12u,=> Y/X=u-1/8u,（你看u=3带入x,y.公约为3,=5,公约为6.）x,y正整数 =>公约不定.2）同上理：Y/x=8Z+1/Z 无论z是几,公约都只是1 gmat的题吗,
3+2<4+5You can only apply subtraction when their signs are in the opposite directions:If a>b...
