45X=60(X-1)
45X=60(X-1)
45X=60(X-1)
45X=60(X-1)
45x=60x-60
60x-45x=60
15x=60
x=4
45x=60(x-1)
45x =60x-60
60x-45x=60
15x =60
x=4
45X=60X-60
45x-60x=-60
-15x=-60
x=4
45X(x+1)=60X 怎么解
45X=60(X-1)
x*x*x*x+2008x*x+2007x+2008(提示:x*x*x-1=(x-1)*(x*x+x+1))
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
(45% x + 15) / x = 60% x怎么解
x/45+x/90-x/60=1 解方程
请问这道题咋做 :(x)X (x+1) X (x+2) X (x+3) =360
45x+10 =50X(x-1)
x/45=(x+30)/60+1 x=270x/45=(x+30)/60+1x=270
x(x-1)(x+1)=60
x/(120-x)=x/60
一元二次方程解答!x(5x+4)=5x+44x^2-45=31x-3x^2+22x-24=0(x+8)(x+1)= -12(3x+2)(x+3)=x+14
12+60%x=48 x-25%x=25 30%x+45%x=27 (1+40%)x=7
x/45=1+(x+30)/60
X/45=(X+30)/60-1
x/60=(x-1)/45
(x-15)/45=(x/60)+1
已知x除以(x*x-x+1)=7,求x*x除以(x*x*x*x+x*x+1)的值
