x÷6×2+x÷5×2=x-600
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
2x^2-4x/x+2`x^2+2x/x^2-4x+4÷x/3x-6,其中x=根号3/2
计算:(x^3-3x^2)/(x^2+5x+6)÷(x^3-9x)/(x^2+2x-3)*(x+2)/(2x)
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
2x+3x+4x+5x+x+6x+7x=100
((x²-5x+6)/(12-7x+x²))²÷((x²+3x+2)/(x
(x+1-1/1-x)÷(x-x²/x-1) (x-4/x-x-6+ x+2/x-3)÷x+1/x-3
x÷2+x÷5+x÷6=1066 求x等于多少
已知(x-根号2+1)(x-2)=0,求代数式[(x-1)/(x-3)-(x-4)/x]÷(x^2+x-6)/(x^2+
已知x²+3x-1=0 求(x-3)÷(3x²-6x)÷(x+2-[5÷(x-2)])的值
1.若x^2+3x-1=0,则x-3/3x^2-6x÷(x+2 - 5/x-2)=________.
先化简,再求值:x^2-5x+6/3x^2-3x÷(1-3/x+1)(1+2/x-3),其中x=2.
