(x^2-3x+1) (x^2+3x+2)( x^2-9x+20)= -30求X
X-30%X+8-X=20
30%x=50%x-20x
(16x-13)/(4x-3)-(20x-24)/(4x-5)=(32x-30)/(8x-7)-(40x-43)/(8x-9)求x
(x+30)*(x-18)=x*x
20%x+20%x×30%x-20%x=4.5
(X+X)+(X-X)+(X*X)+(X/X)=100
50%x+x=20 x+30%x=52
x-30%x=14x+25%x=20
x+3x-(9x+30x)=98
x/6+x/12+x/20+x/30=1
(30-x):(18+x)=(20+x):(32-x)
x-3(20-x)=3x-7(9-x)
x/30+x/20=9,x=?
解方程(x^2-3x+1)(x^2-3x+2)(x^2-9x+20)=-30
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)....
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)
x/x-2+x-9/x-7=x+1/x-1+x-8/x-6,
