3(2x-1)+2(4x-6)=5(2x-5)+40(要详细)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
解方程:3(4x-9)-2x=6-x 要详细步骤
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
4x-2(10-x)=5(4-x)-3[10-(4-x)】+10咋解详细
3x²+5x+2=4x²+3x-().急!求详细过程
6/(x+1)=(x+5)/[x(x+1)] (3-x)/(x-4)+1/(4-x)=1 2/(1+x)-3/(1-x)
5x-3(2x+1)=6x-4(5-3x)求x
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
X-(X/2)+(X/3)-(X/4)+(X/5)-(X/6)=1
x(x^2-1)+2x^2 *(x+1)-3x*(2x-5)=x(3x^2-4x)-28
