6(x+1)=0.5(10x+16)
6(x+1)=0.5(10x+16)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
解方程:2x(x-2)-6x(x-1)=4x(1-x)+16.
3/x-1=4/x 6/x+1=x+5/x(x+1)
(x+1分之x+6)-(x^+3x+2分之3x^+10x+4)+(x+2分之2x+1)=0,解这个方程
先化简再求值先化简再求值:(x-x/x+1)(x+1/x^2+4x+4)(x^2-4/x^2-2x),其中x=-0.5
2X+4(8-X)=20 10X-6(10-X)=36 10X-6(16-X)=64 0.5X+0.1(8-X)=2 4
若1+x+x*x+x*x*x=0,求x+x*x+x*x*x+.+x(2000次幂)
6X-(360X-0.5X)=2×(360X-0.5X)
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
