x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
2x+3x+4x+5x+x+6x+7x=100
15%x+30%x+5%x=6/5
(x+7/x+6) +(x+9/x+8)=9x=(x+10/x+9) +(x+6/x+5)
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
(X-5)(X-6)=X-5
3x+5x-6x=?
x^-6x+5=x+4
(x+8)(x+6)(x+7)+(x+5)(x+6)(x+7)=(x+5)(x+8)(x+7)+(x+5)(x+8)(x+6)
先观察下列各式,(x+5)(x+6)=x²+11x+30 (x-5)(x-6)=x²-11x+30先观察下列各式,(x+5)(x+6)=x²+11x+30(x-5)(x-6)=x²-11x+30(x-5)(x+6)=x²+x-30(x+5)(x-6)=x²-x-30(1)乘
5X+6(X+10)+10(X+30)+6(X+70)+3(X+150)=2730,X等于多少
x/2+x/6+x/12+x/20+x/30=5x/2中/是分数线
7x-5*(6-x)=30
30%x(x-5)=6
