6+[0.5^(4/5)+(5/13-x)^9]/4=22
(4x+2)/x+(4x-22)/(x-5)=(x-6)/(x-4)+(7x+9)/(x+1)
1x+2x+3x+4x+5x+6x+7x+8x+9x+10x+11x+12x+13x+14x+15x=550
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
x-4/x-5 - x-5/x-6=x-7/x-8 - x-8/x-9求x=?
求方程解x-5/x-4+x-9/x-8=x-8/x-7+x-6/x-5
x-4/x-5-x-7/-x-8=x-5/x-6-x-8/x-9
解分式方程:(x-4)/(x-5)+(x-8)/(x-9)=(x-7)/(x-8)+(x-5)/( x-6)
解分式方程(X-4)/(X-5)-(X-5)/(X-6)=(X-7)/(X-8)-(X-8)/(X-9)
解方程:(x-4)/(x-5)-(x-5)/(x-6)=(x-7)/(x-8)-(x-8)/(x-9)
