解答
移项 3X+5Y-13=根号3(Y-2X)
因为无理数不等于有理数
所以 3X+5Y-13=0, Y-2X=0
X=1,Y=2
推荐
- 已知x、y都是有理数,且y=根号x-3 +根号(3-x) +3,求y^(x+1)
- 已知x、y是有理数,且x、y满足2x^2+3y+y根号=23-3根号2,则x+y=1或-7 我要过程
- 已知x,y是有理数,且(1/3+3/2)x+(1/4-(根号3)/12)y-2.25-1.45根号3=0,求x,y的值
- 已知x、y为有理数,且x+y倍根号2=3-2倍根号2,求x、y的值
- 已知x、y是有理数,且(3-根号2)x+(5+根号2)y=19-根号2,求x和y的值
