解方程:2x+4x+6x+8x+...+2010x+2012x=1013042
解方程2x+4x+6x+8x~+2010x+2012x=1013042
求方程解x-5/x-4+x-9/x-8=x-8/x-7+x-6/x-5
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)
解方程:x-4/x-5 -x-5/x-6=x-7/x-8 -x-8/x-9
