(x+10%)×5=100
(2x-2)(x-1)=0 x(x-5)=5x-10
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
帮我解几道方程、、8x-4(10-x)=44 60x+(100-x)*65=100*63 30x-20(180-x)=5
(X/80+X/100 +5)*40=X,
1)x+1/x=3,求x^10+x^5+1/x^5+1/x^10的值
(x-6)/(x-5)-(x-7)/(x-6)=(x-9)/(x-8)-(x-10)/(x-9)
计算:1/(x^2-7x+10)+1/(x^2-x-2)+1/(x^2+5x+4)+1/(x^2+11x+28)=( )
2x+3x+4x+5x+x+6x+7x=100
(x+12)(x-2)+(x+7)(x+8)-(x+5)(x-10),其中x=2
(X+X)+(X-X)+(X*X)+(X/X)=100
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
X-2/5X-[(X-2/5X)*5/9-10]=74
