谁能吧(x+3X-32)*3/7=3X-32 解出来
谁能吧(x+3X-32)*3/7=3X-32 解出来
(4/7x-12)+3/2(4/7X-12)=X 解出来
x/(x-3)=(x+1)/(x-1)解出来等于多少!
2x(7-3x)+5x(2x+1)=x(4x-3)+32
用递归法求y=x-(x*x*x/3!)+(x*x*x*x*x/5!)-(x*x*x*x*x*x*x/7!)+.
3X+4y=5 6X+7y=8 解出来.
怎么把3x+2(12-x)解出来啊?
解方程(x-2)/(x-3)-(x-3)/(x-4)=(x-5)/(x-6)-(x-6)/(x-7)
解方程】(x+8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
解方程:(x+3)/(x+2)-(x+5)/(x+4)=(x+7)/(x+6)-(x+9)/(x+8)
解分式方程 x-7/x-9+x-3/x-5=x-4/x-6+x-6/x-8
