4(2x+3)=8(1-x)-5(x-2).
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
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)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
x(2x-5)>2x的平方-3x-4 (x+1)(x-3)+8x>(x+5)(x-5)-2 解不等式组
x(x^2-1)+2x^2 *(x+1)-3x*(2x-5)=x(3x^2-4x)-28
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
3X+(X+2)+(X+1)*(X-1)=4*(X²+8)
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
x^5+x^4 = (x^3-x)(x^2+x+1)+x^2+x
