3x=45÷x

3x=45÷x 化简 [3x/(x+2)-x/(x=2)]÷x/(x^2-4)化简 [3x/(x+2)-x/(x-2)]÷x/(x^2-4 X×X－3X＋1=0求分式X×X÷〈X×X×X×X+3X×X+1〉 X^2-3X-2=0,求( x - 2x-1/x )÷(x-1)/(x^2-2x) (x-5)+(x-3)+x+(x+3)+(x+5)=45,x等于? (4/x-5)+(x-3)/(12-x)=(x-45)/(x^2-17x+60) 用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+. x(2-1/x)+x/(x^2-2x)÷(3-x)/(x^2-4)2.2/3+x/(3x-1)=1/9x-3 2x^2-4x/x+2`x^2+2x/x^2-4x+4÷x/3x-6,其中x=根号3/2 2x^2-4x/x+2`x^2+2x/x^2-4x+4÷x/3x-6,其中x=根号3/2 化简求值：(3x/x+2-x/x-2)÷2x/x^2-4,x=-3 x=根号3时,代数式（x/x-1-x/x+1)÷2x/1-x的值是? 先化简,再计算2x^-18/4-4x+x^ ÷ 3-x/x^+x-6,其中x=4 先化简再求值[3x/(x+2)-x/(x-2)]÷2x/(x^2-4)x=2010 (x+x)+(x-x)+(x*x)+(x÷x)=81 【化简求值】(x分之x+2 - x-2分之x-1)÷x分之x-4【化简求值】(x分之x+2 - x-2分之x-1)÷x分之x-4x=3 ｜x｜÷(x-3)与(3-x)÷x为相反数,则x=_____ 8x^2-4x/x^2-x-6÷(x-3/x+2-x+2/x-3),其中x=5
