(x+6)*(x+6)-x*x=132算出X等于几(x+6)*(x+6)-x*x=132算出X等于几(x+6)*(x+6)-x*x=132算出X等于几x^2+12x+36-x^2=13212x=96x
(x+6)*(x+6)-x*x=132算出X等于几
(x+6)*(x+6)-x*x=132
算出X等于几
(x+6)*(x+6)-x*x=132算出X等于几
x^2+12x+36-x^2=132 12x=96 x=8
(x+6)*(x+6)-x*x=132算出X等于几
x*x-(x+6)*(x+6)=132算出X等于多少即可
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?
x(x*x-6x-9)-x(x*x-8x-15)+2x(3-x)
填九宫格帮帮忙.x x 6 x x 7 x x 98 x x x 3 x 1 x x 9 x x 6 x 5 x 3 x x x 3 x x x x 1 8x x x 9 x 1 x x x2 1 x x x x 6 x x x 6 x 7 x 3 x x 1 x x 9 x 2 x x x 47 x x 8 x x 5 x x
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+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=?
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
X(x平方-6x-9)-x(x平方-8x-15)+2x(3-x)其中x=-六分之一
X-0.8X=6 X=?
