X-(X/2)+(X/3)-(X/4)+(X/5)-(X/6)=1
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
3/x-1=4/x 6/x+1=x+5/x(x+1)
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)
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
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
1、x*(x+3)*(x+6)*(x+9)=68040 2、x*(x+1)*(x+2)*(x+3)*(x+4)=5544
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)
