175
125
没太看懂,能用文字表达一下么?
7/xx+x+1/xx-1=2/xx-x

解方程:75%X+25%XX[800-X]=8000X45%
解方程:75%X+25%XX[800-X]=8000X45%
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
x/xx+x+1=1/4 求xx/xxxx+xx+1
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表示1-9的数,x13/xx=xx,1748/xx=xx,x不能重复
100xX(1+25%)+80(2800-X)乘(1+10%)=3140,x=多少
(x+x)+(x-x)+(xx)+(x/x)=100 求x的值?用方程解
(x-y)(x+y)(xx-yy)=?
XXX*XX=XX*XX=3624,X内填写1-9,数字不能重复
已知xx+x-1=0,求:xx+1/xx,xxxx+1/xxxx
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)
