160乘25%-1.3x=17.9 x/5-x/6=0.4 3(x+2)=40+11 0.3/0.5=x+1/2x-1 2.5/（x—0.5）=25% 1/3:0.25=80%：x
160乘25%-1.3x=17.9
x/5-x/6=0.4
3(x+2)=40+11
0.3/0.5=x+1/2x-1
2.5/（x—0.5）=25%
1/3:0.25=80%：x
160乘25%-1.3x=17.9
x/5-x/6=0.4
3(x+2)=40+11
0.3/0.5=x+1/2x-1
2.5/（x—0.5）=25%
1/3:0.25=80%：x
160*25%-1.3x=17.9
1.3x=40-17.9
x=22.1/1.3
x=17
再问： x/5-x/6=0.4 3(x+2)=40+11 0.3/0.5=x+1/2x-1 2.5/（x—0.5）=25% 1/3:0.25=80%：x 帮帮忙啊！ 急啊

x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
(2x-1)/(x-1)(x-2)=(x-5)/(x-2)(x-3) x/2x^2-11x-21=(x+7)/x^2-1
y=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10)的导数在x=1
已知1+x+x^2+x^3=0,求x+x^2+x^3+x^4+x^5+x^6+x^7+x^8的值
设函数f(x)=(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)(x-8)(x-9)(x-10),
解方程(x+1/x+2)-(x+2/x+3)=(x+5/x+6)-(x+6/x+7)
解方程：x+2/x+1-x+3/x+2=x+6/x+5-x+7/x+6
x-1\x-2+x-6\x-7=x-2\x-3+x-5\x-6 分式方程
（1） x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
