7x-3(2/3x+1/5x)-(x+2/5x)+2x,=5x怎么求出
4+6X(3x-2)=16x 怎么解方程?注备:X=乘 x=x
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
解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7)
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
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
解方程:2(X-3)(X+5)=X平方+(X+2)(X-2)+(X+7)
