(2x-1)/0.7=x/0.3-1/7
7x-3=6x-5
2-2/3x=x-3/2
3x-(x-1)=510+2(x-1/2)=7(x-2)
1-(38x-2)/19=(2-3x)/3
3x-(3x-1)=x/6

X=27;
补充问题：
1 X=-2;
2 X=2.1;
3 补充里的第三个出错了
4 X=25/57;
5 X=6;
补充里的3应该是2个式子从5那断开的话
X=3; X=4.6

(x+7)(x+6)-(x-2)(x+1)=? X-5+8*X=7*X-2*X-1 (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的值已知1+x+x^2+x^3=0,求x+x^2+x^3+x^4+x^+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), (3-x)/(1-x)-(5-x)/(7-x)+(x^2-x)/(x^2-8x+7)=1 x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)谁会解这道方程题分式方程.x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6) x/(x-2)+(x+9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)怎样解这道方程解方程：x/(x-2)+(x-9)/(x-7)=(x+1)/(x-1)+(x-8)/(x-6)
