(1)4(x+1)-5(x-1)=1 (2)3(x+5)=x-1/4 (3)3x+1/5-1=x+10/3 (4)2x+5-x+1/6=2x-4/3
(1)4(x+1)-5(x-1)=1 (2)3(x+5)=x-1/4 (3)3x+1/5-1=x+10/3 (4)2x+5-x+1/6=2x-4/3
(1)4(x+1)-5(x-1)=1 (2)3(x+5)=x-1/4 (3)3x+1/5-1=x+10/3 (4)2x+5-x+1/6=2x-4/3
（1）4x+4-5x+5-1=0 x=8
（2）3x+15-x+1/4=0 2x=61/4 x=61/8
（3）2x=10/3+1-1/5=62/15 x=31/15
（4）-x=-4/3-1/6-5=-23/6 x=23/6
(1)x=8
(2)x=-61/8
(3)x=31/15
(4)x=13/2
(1) 4(X+1)-5(x-1)=4(x-1+2)-5(x-1)=4(x-1)+8-5(x-1)=4(x-1)-5(x-1)+8=-1(x-1)+8=8-(x-1)=9-x=1
X=8
(2) 3(x+5)=x-1/4 3x+15-x+1/4=0 2x+15+1/4=0 x=—(15+1/4)÷2=—61/8
(3) 3x+1/5-1=x+10/3 3X-x=-1/5+1+10/3 2x=62/15 x=31/15
(4) 2x+5-x+1/6=2x-4/3 2x-x-2x=-5-1/6-4/3 -x=21/6 x=—7/3

(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)
x(x+1)+(x+2)+(x+3)+(x+4)+(x+5) = 27求x
提取公因式:已知x*x-5x+1=0 求x*x*x-4x*x-4x-1
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
写过程x(x-1)+2x(x+1)-3x(2x-5)-x(3x-2)+2x(2-x)=-5x(x-2)-4
x+2/x+1-x+3/x+2-x+4/x+3+x+5/x+4
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11+x^12=97.8 好多年没有用过过数学公式了 想不起来怎么算了 想知道 X值是多少
已知x=2π+1求 |x-1|+|x-2|+|x-3|+|x-4|+|x-5|+|x-6|+|x-7|+|x-8|+|x-9|+|x-10|
x^5-x^4+x^3-x^2+x-1
x^6-x^5+x^4-x^2+x-1
已知x=2π+1.求(X-1)+(X-2)+(X-3)+(X-4)+(X-5)+(X-6)+(X-7)+(X-8)+(X-9)+(X-10)
1+x+x^2+x^3+x^4+x^5+x^6+x^7+x^8+x^9+x^10+x^11=17.7这个方程怎么样求解?
如果1+x+x^2+x^3=0,求x+x^2+X^3+x^4+x^5+x^6+x^7+x^8的值,
(4x+2)/x+(4x-22)/(x-5)=(x-6)/(x-4)+(7x+9)/(x+1)
(x+1)(x+2)(x+3)(x+4)-(x^2+5x+3)(x^2+5x+7)=?
(x+2)/(x+1)-(x+3)/(x+2)=(x+4)/(x+3)-(x+5)/(x+4)
x-1/x-2-x-3/x-4=x-2/x-3-x-4/x-5怎么做?
