用换元法解一道方程题(x+9)/x -8 = 16x/-9-x
用换元法解一道方程题(x+9)/x -8 = 16x/-9-x
x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)谁会解这道方程题
一道数学分式方程(x-4)/(x-3)-(x-6)/(x-5)=(x-8)/(x-7)-(x-10)/(x-9)
问一道方程题!x的平方+4x-9=2x-11
⒈ 解方程 (X+7)/(X+6)+(X+9)/(X+8)=(X+10)/(X+9)+(X+6)/(X+5)
求方程解x-5/x-4+x-9/x-8=x-8/x-7+x-6/x-5
解方程: x-5/x-6+x-8/x-9=x-7/x-8+x-6/x-7 过程!
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解分式方程:(x-4)/(x-5)+(x-8)/(x-9)=(x-7)/(x-8)+(x-5)/( x-6)
解分式方程(X-4)/(X-5)-(X-5)/(X-6)=(X-7)/(X-8)-(X-8)/(X-9)
解方程:(x-4)/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)
