x+(x+24)+(x+24)/2=7x
x+(x+24)+(x+4)/2=7x
x+(x+24)+(x+24)/2=7x
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
(x+24)+x+(x/2+12)=7x 怎么解
(x*x-5x)(x*x-5*x-2)-24分解因式
(1/7x+24)/2=x-1/7x-(1/7x+24) 解方程 (x为未知数)
(x/x-1)+(5x-2)/x*x-x=1 求x(有图)
初一数学x*x+2x+5的值为7,请求3x*x+6x+3的值.因为x*x+2x2x+3=3x(x*x+2x)+2x+2x
4x+7x=150-7 19x-5(3x-4)=24 2(4x-3)+(15-2x)=24+12
5x/(x+3)(x+2)+(2x-5)/(x-4)(x+3)=(7x-70)/(x+2)(x+4)
解方程.(5x/x²+x-6)+(2x-5/x²-x-12)=7x-10/x²-6x+8
