(-8)x(-5)x(0.125) (-1/12-1/36+1/6)x(-36) (-5)x(+2
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
化简 x(x-1)+2x(x+1)-3x(2x-5)
3/x-1=4/x 6/x+1=x+5/x(x+1)
x(x平方-1)+2X平方(X+1)-3X(2X-5)帮个忙
x(2x-5)>2x的平方-3x-4 (x+1)(x-3)+8x>(x+5)(x-5)-2 解不等式组
6/(x+1)=(x+5)/[x(x+1)] (3-x)/(x-4)+1/(4-x)=1 2/(1+x)-3/(1-x)
x+1分之x+2减去x+3分之x+4=x+5分之x+6减去X+7分之x+8 (解方程)
5x-3(2x+1)=6x-4(5-3x)求x
(x-1)/x -(1-x)/(x+1)=(5x-5)/(2x+2) x等于多少
