x=5,y=110{x=y/x; y=y-x;}while(y>=1); 求x y 已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y) 二元函数f(x,y)=x+y/x-y,求f(y/x,x/y) 求y'=y/(y-x) 已知：4x = 5y,求(x+y) ：y 已知X-Y/X+Y=3,求代数式2(x-y)/X+Y-3X+Y/X+Y 若x-y=1,求代数式x(x-y)+y(y-x)+2013的值 已知4x=9y求(1)x+y/y (2)y-x/2x x=1 y=2 do x=x*y y=y+1 loop while y X=2 Y=4 Do x=x*y y=y+1 Loop While y x+y=5; x^y+y^x=17 已知x=1/3,y=-1/2,求代数式x-(x+y)+(x+2y)-(x+3y)+(x+4y)-(x+5y)+...-(
