解方程48-8X=4(X-2) 9(X-8)=11X-8(X-2)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程48-8X=4(X-2) 9(X-8)=11X-8(X-2)
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
x+4x+8=4x+11 x(2x-4)=5-8x解方程急!
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
解方程1/x(x+1)+1/(x+1)(x+2)+...+1/(x+8)(x+9)=2x+3/x(x+9)
解方程:1\x(x+1)+1\(x+1)(x+2)+.+1/(x+8)(x+9)=2x+3\x(x+9)
解方程 x(2x-4)+3x(x-1)=5x(x-3)+8
解方程:2x+4x+6x+8x+...+2010x+2012x=1013042
解方程2x+4x+6x+8x~+2010x+2012x=1013042
解方程:x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
