解方乘:(1)5(X—8)=3X (2)9(2X—3)—2=5(2X—1)
(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)
解方程(x-2)X(x的平方-6x-9)=x(x-5)X(x-3)
解方程1/x(x+1)+1/(x+1)(x+2)+...+1/(x+8)(x+9)=2x+3/x(x+9)
解方程:1\x(x+1)+1\(x+1)(x+2)+.+1/(x+8)(x+9)=2x+3\x(x+9)
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
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
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)
已知 |x+2|+|2x—3|=5—x 化简(x-4)√(4x²-12x+9)+(1+2x)√(x²
