有人这样解方程:2(2x-4)-12=10(x-5)解:4x-8-12=10(x-5),4x-20=10(x-5)由乘法
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
解方程:(2x+5)(4x*x-10x+25)=8x(x*x+1)
解方程(x/x(x+2))+(x/(x+2)(x+4))+.+x/(x+8)(x+10)=1
解方程:1/x(x+2)+1/(x+2)(x+4)+……+1/(x+8)(x+10)=5/24(x+10)
解方程3x=x+4,2.6x-8=2.4x,4x+12=10x+3 ,7x=12-×,2.5x=2x+4,5x+3=6x
x+4x+8=4x+11 x(2x-4)=5-8x解方程急!
解方程:1/x(x+2)+1/(x+2)(x+4)+...1/(x+8)(x+10)=5/24.
解方程 x(2x-4)+3x(x-1)=5x(x-3)+8
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/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(5-2x)/(x^2-x-12)=5x/(x^2+x-6)+(10-7x)/(x^2-6x+8)得
