X:2/3=4/5x-2/3x=2/9
X:2/3=4/5
x-2/3x=2/9
X:2/3=4/5x-2/3x=2/9
X:2/3=4/5
x=4/5 × 2/3
x=8/15
x-2/3x=2/9
(1-2/3)x=2/9
1/3 × x=2/9
x=2/9 ÷(1/3)
x=2/3
X=8/15 x=2/3
x=(4/5)×(2/3)=8/15
x=2/3
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
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?
(x-3/x-2)-(x-2/x-1)=(x-5/x4) -(x-4/x-3)

写过程x(x-1)+2x(x+1)-3x(2x-5)-x(3x-2)+2x(2-x)=-5x(x-2)-4
xy²/(x²y-y) × x²/(x²+x)=(x²-3x)/(x²-5x) × 2x-10/(x²-6x+9)=化简求植x²-1/(x²-x-2)除以x/2x-4,其中x=1/2[x-x/(x+1)]除以[x/(2x-4)] ,其中x=√2+1
1x()+2x()+3x()+4x()+5x()+6x()+7x()+8x()加9x()+10x()=1980
1X?+2X?+3X?+4X?+5X?+6X?+7X?+8X?+9X?+10X?=1980求?是多少
matlab中a(x)=x^4+3x^3+9x-18 b(x)=x^5-4x^3-18x+7 c(x)=x^7+6x^5+9x^3-5x^2-2 d(x)=x^9-8x^7+6x^5-4x^4+d(x)=x^9-8x^7+6x^5-4x^4+6x^2+3 求e(x)=a(x)*b(x)*c(x)*d(x)
