(7/5)x-(1/3)x=(9/4)
(1) x-3/x-2 - x-5/x-4=x-7/x-6 - x-9/x-8
(3x^2+9x+7)/(x+1)-(2x^2-4x+3)/(x-1)-(x^3+x+1)/(x^2-1)是不是错了?
(x+2/x+1)-(x+4/x+3)-(x+3/x+2)+(x+5/x+4)
计算(x*x+4x+5)/(x+2)-(x*x+6x+10)/(x+3)+1
解方程:(x-8)/(x-3)-(x-9)/(x-4)=(x+7)/(x+8)-(x+2)/(x+3)
|X-1|+|X-2|+|X-3|+|X-4|+|X-5|+|X-6|+|X-7|+|X-8|+|X-9|+|X-10|
3/x-1=4/x 6/x+1=x+5/x(x+1)
数学题(x-4)/(x-3)+(x-6)/(x-5)=(x-8)/(x-7)+(x-10)/(x-9)解方程,
解方程:x(2X-3)+2x(x-1)=4x(x-2)+9
方程 3x(7-2x)+5x(2x-1)=4x(x-3)+56
3x-4(2x+5)=7(x-5)+4(2x+1)
化简(-2x^2)+3x+2)-3(7x^2-5x-1)-(4x^2-x+6)
