当x为何值时,代数式(2x+9)/(x+3)-1/(x-3)与2+2/x的值相等?
当x为何值时,代数式(2x+9)/(x+3)-1/(x-3)与2+2/x的值相等?

当x为何值时,代数式(2x+9)/(x+3)-1/(x-3)与2+2/x的值相等?
化简代数式:(2x+9)/(x+3)-1/(x-3)=(2x+6+3)/(x+3)-1/(x-3)=2+3/(x+3)-1/(x-3)
所以:3/(x+3)-1/(x-3)=x/2,去分母得:12x=18,x=3/2.

3+3+33+3-++-3+3-3+3-+-33-----3+-+-4+66-56+-5+65-6+5-6+-5+6-5-+6-56+-56+-5-6+-56+--4+-79+12487+9-8-+7=546454

x=3/2
