1,5,14,30,55,91,xx=?运算方法
7/xx+x+1/xx-1=2/xx-x
解方程1/(xx+x)+1/(xx+3x+2)+1/(xx+5x+6)+1/(xx+7x+12)+1/(xx+9x+20)=5/(xx+11x-7
解方程1/(xx+x)+1/(xx+3x+2)+1/(xx+5x+6)+1/(xx+7x+12)+1/(xx+9x+20)=5/(xx+11x-708)
解方程:3x/(xx-1)+(xx-1)/3x=5/2
用你喜欢的方法计算25/28-(2/7+5/14)4/9+4/7+3/7+4/915/8-(14.8+2/3)应该是能脱式计算之类的,能简便就简便.格式应该是:XX-(XX+XX)=XX+XX-XX=XX不要解析,但内容必须是对的而且过程详细.
data=xx[i]>>1
x表示1-9的数,x13/xx=xx,1748/xx=xx,x不能重复
1,2,3,4,5,6,7,8,9,九个数字XX除X=XX除X=XX除X
已知xx+x-1=0,求:xx+1/xx,xxxx+1/xxxx
x/xx+x+1=1/4 求xx/xxxx+xx+1
XXX*XX=XX*XX=3624,X内填写1-9,数字不能重复
xx+2xy+yy=1 xx-2xy+yy=49 求xx+yy,xy.
已知x/(xx+x+1)=a,求xx/(xxxx+xx+1)的值
已知:3x=xx-x+1求(xxxx+xx+1)分之xx
7/(XX+X)+1/(xx-x) =6/(xx-1)
解分式方程7/(XX+X)+1/(xx-x) =6/(xx-1)
7/(XX+X)+1/(xx-x) =6/(xx-1)
