1X/4+(180-X)=6/5(180-X)怎么解
1X/4+(180-X)=6/5(180-X)怎么解
1X/4+(180-X)=6/5(180-X)怎么解
1X/4+(180-X)=6/5(180-X)
乘以20得 5x+20(180-x)=24(180-x)
5x=4(180-x)
5x=720-4x
9x=720
x=80

x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
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|
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)
解方程 x+2/x+1+x+8/x+7=x+6/x+5+x+4/x+3
解方程:2x+4x+6x...+100x=1-(x+3x+5x+...+99x)
(x-1)(x-2)(x-3)(x-4)=(x+5)(x+6)(x+7)求X等于几?
x-2/x-1+x-8/x-7=x-4/x-3+x-6/x-5
(X+2)/(X+1)-(X+4)/(X+3)=(X+6)/(X+5)-(X+8)/(X+7)
解方程 (x+2)/(x+1) - (x+4)/(x+3)=(x+6)/(x+5)-(x+8)/(x+7)
1x+2x+3x+4x+5x+6x+7x…+99x=100
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7
3/x-1=4/x 6/x+1=x+5/x(x+1)
1x 2x 3x 4x 5x 6=( )x( )+( )
