3道简单的分式方程,1.3/(1-x^) = 2/(1+2x+x) - 5/1-2x+x^2.5x/(x^+x-6) + (2x-5)/(x^-x-12) = (7x-10)/(x^-6x+8)3.(x+1)/(x+2) + (x+6)/(x+7) = (x+2)/(x+3) + (x+5)/(x+6)
1.(x*2-3x+3)/(x*2-3x+2)-(x*2-5x+7)/(x*2-5x+6)-1/(x*2-4x+3)2.1/x(x+1)+2/(x+1)(x+3)+3/(x+3)(x+6) 3.已知:x*2-3x+1=0,求x*2+1/x*2.
解方程、不等式 1.8-2x=5-x 2.8-2x<5-x 3.{y+2x=8 x+y=5 第3...{y+2x=8 x+y=5
计算:1.6x-1/3x+2=5x-7/2x-5 2.2x/x-1=2/x+2=2 3.x-1/x+1-x/x-1=4/x²-1
1.f(x)=x(x^2+1/x+1/x^3) 2.f(x)=(e^x+Inx)/x 3.f(x)=sinx(cosx+2^x) 4.f(x)=5log2(2x+1)
已知x-x-1=0,证明.x=2x+1,x的五次方=5x+3.
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
5x-x=2.4 1.5x-x=1 6.6x-6x=1.8 2x-2/3x=3/4 解方程
1.x+9/x+8- x+10/x+9=x+6/x+5- x+7/x+6;2.x³+2/x²-x+1+ x³-9/x²+2x+4=2x-1;3.x-a-b/c+ x-b-c/a+ x-c-a/b=3.(空开的指另一个分式)第二题不用了。
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
x(x-2)-2x(x+1)-3x(x-5) 其中x=负½
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
x-2x+3x-4x+5x.+99x-100x=25求解

x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
f(x,-x)=x^2+2x,fx(x,-x)=5x+1,则fy(x,-x)=
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
