2^x=3yx,y均为整数,求x,yx,y是正整数
已知x-3y=0,求2x+yx
若|x-y+3|与|x+y-1999|互为相反数,求x+2yx−y
当x−yx+y
若x+y=4,xy=3,求yx
若|x-y+3|与|x+y-1999|互为相反数,求x+yx−y
已知y=根号3-x+根号x-3 +2, 求yx次方的立方根?
y=根号x-2+根号2-x-3求Yx次方的平方根
已知3x2+xy-2y2=0,求(x+yx-y+4xyy
已知2x2-xy-3y2=0,求x−yx+y
跪求-3y²-2yx+x²因式分解的详细过程T^T!
matlab求x,yx*3012=x*1406+y*1753+202480 x+yx*3012=x*1406+y*175
设实数x,y满足条件x≥0x≤yx+2y≤3
