XX+X-X=XX*X=XXX为1到9数字,不能重复XX+X-X=XX*X=XXX为1到9数字,不能重复XX+X-X=XX*X=XXX为1到9数字,不能重复12+3-8=76*9=54212+3-8=
XX+X-X=X X*X=XX X为1到9数字,不能重复
XX+X-X=X X*X=XX X为1到9数字,不能重复
XX+X-X=X X*X=XX X为1到9数字,不能重复
12+3-8=7 6*9=54
2
12+3-8=7
6*9=54把7、8换一下得到第二个答案
题目是 (1) XX*X=XX X*X=XX X为未知数分别将1到9的9个数填入不能重复 *为乘号 (2)XX/X=X X/X=XX/ X X为
XX+X-X=X X*X=XX X为1到9数字,不能重复
7/xx+x+1/xx-1=2/xx-x
X/X=X/XX=XX/XX 注:X为1到9不重复的数字,这道题目怎么解答!
x/xx+x+1=1/4 求xx/xxxx+xx+1
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)
(x-y)(x+y)(xx-yy)=?
x表示1-9的数,x13/xx=xx,1748/xx=xx,x不能重复
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)
(x+x)+(x-x)+(xx)+(x/x)=100 求x的值?用方程解
xx而x 七x八x xx忘x
已知X*X-5X+1=0,求X*X+1/XX的值
小数奥数网xx(x +1)x(x+ 2)x(x +3)=360怎样算?
