x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
2x+3x+4x+5x+x+6x+7x=100
(x/x-2)+(2/x*2+2x)-(x+6/x*2-4)化简,=x^2/x(x-2)+(2x-4)/x(x^2-4)-(x^2+6x)/x(x^2-4)=x^2/x(x-2)-(x+2)/x(x-2)=(x-2)(x+1)/x(x-2)=(x+1)/x
x^-6x+5=x+4
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
1.用公式计算：COSX=1-X*X/2!X*X*X*X/4!-X*X*X*X*X*X/6!.直到最后一项的绝对
4.2-0.6x=3.6x 5x+2x=33.6 7x-4x=0.75 2x+7x+2.1=12 56x-32x-119=361 x+5=2x 3x+9=6x 4x-28=2x 2x+18=7x 5x=25*4-15x 7x-x+2*3=29.4 (28.8+5.5x+3.2）除2=71

4x^-4x+1=x^+6x+9
4x-4x+1=x+6x+9
6x+4x+8x=32 x=?
4^x-6^x-9^x=0 x=?
x:(6+x)=4:
27046=2x( )+7x( )+4x( )+6x( )
[3/x]-[4/x-1]=6/x-x²
X+X-6+X-4+X/2=60
[3/x]-[4/x-1]=6/x-x²
