If two rational number x,y satisfy |x|+y=3 and |x|y+x*x=0 ,t
If two even number x,y satisfy equation x×x+100=y×y,x
if ( x< y ) { t=x; x=y; y=t; } 怎么理解呢?
X=5 y=-20 If not x>0 then x=y-3 else y=x+3 print x-y;y-x end
GMAT If x and y are positive integers,and x^3*y^4=2000.What
4.3(10分)阅读以下程序代码 if (y > 0 and x > 0) while (x > y) do x = x
x=5 y=-20 IFx<0 THEN x=y-3 ELSE y=y+3 END IF PRINT x-y;y-x E
int x=1,y=0; if(!x)y++; else if(x==0) if(x)y+=2; else y+=3;
已知|3x-y|+|x+y|=0,求x-y除以x*y的值.
main() { float x,y; scanf(%f,&x); if(x>=0) y=x; else y=-x; p
已知X-Y/X+Y=3,求代数式2(x-y)/X+Y-3X+Y/X+Y
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
x>1,y>0,且满足xy=x^y,x/y=x^3y,求x+y
