(54+x)*5/6 = 24+x 咋解,
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
解方程x/(x-2)=2x/(x-3)+(1-x)/(x-5x+6)
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
方程题 6x+27=3X+54 7x-4=24+3x x+5=2x+36
(X-5)(X-6)=X-5
5x+6(3x+2)(-2+3x)-54(x-1/3)(x+1/3)=3 x=?
