6x=36.3-27
6x=9.3
x=1.55
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
int x=6; x += x -= x * x; printf(x = %d
,x);
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
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+7/x+6) +(x+9/x+8)=9x=(x+10/x+9) +(x+6/x+5)
X-0.8X=6 X=?
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=?
3x+5x-6x=?
X乘X=6乘X
(X-5)(X-6)=X-5
A={x|x^2+x-6
x^-6x+5=x+4
260x=200X(x+6)
x-(25%x+6)=60%x
