60%=3/5,则3x+52=35/3x
移项得 (3-35/3)x=-52
--26/3x=-52

3x+52=7x÷60%
3x+52=7x÷60%
3x+52=7x×(5/3)
3×(3x+52)=35x
9x+156=35x
156=35x-9x
156=26x

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!)+.

x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
如果3x*x-x=1那么9x*x*x*x+12x*x*x-3x*x-7x+2001等于多少
2x+3x+4x+5x+x+6x+7x=100
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
已知3x*x-x=1,求6x*x*x+7x*x-5x+2000
3x+7x=( )+( )X( )
(x+7)+x+3x=17
(x+1)/(x+2)+(x+8)/(x+9)解答x+1/x+2+x+8/x+9=x+2/x+3+x+7/x+8

x-3(20-x)=3x-7(9-x)
x-2/3x+x+2/7x=30
(x-7)(x+3)+(x-1)(x+5)=102
(x-7)(x+3)+(x-1)(x+5)=102
