解方程x-8+3(x-8)-2(x-8)+4(x-8)=12
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
x+1分之x+2减去x+3分之x+4=x+5分之x+6减去X+7分之x+8 (解方程)
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.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
解方程:1\x(x+1)+1\(x+1)(x+2)+.+1/(x+8)(x+9)=2x+3\x(x+9)
x+4x+8=4x+11 x(2x-4)=5-8x解方程急!
解方程 x(2x-4)+3x(x-1)=5x(x-3)+8
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
3/8x+(x-3/8x)×2/3+55=x+1/4x 用方程解
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
1/(x+2)(x+4)+1/(x+a)(x+6)+1/(x+6)(x+8)=2/(3x+24) 解方程
