谁会解:(10y+x)/(x+y)=8.7(10x+y)/(10y+x)=4.3谁会解:(10y+x)/(x+y)=8.7(10x+y)/(10y+x)=4.3谁会解:(10y+x)/(x+y)=8.

谁会解:(10y+x)/(x+y)=8.7 (10x+y)/(10y+x)=4.3
谁会解:(10y+x)/(x+y)=8.7 (10x+y)/(10y+x)=4.3

谁会解:(10y+x)/(x+y)=8.7 (10x+y)/(10y+x)=4.3

(10y+x)/(x+y)=8.7
8(x+y)+7=10y+x
7x+7=2y
x,y为小于10的自然数,则x=1,y=7.

(10x+y)/(10y+x)=4.3
4(10y+x)+3=10x+y
13y+1=2x
x,y为小于10的自然数,则x=7,y=1.
