-5(负5)
x+2x+3x+4x+5x+6x+7x+8x+9x=9x-8x-7x-6x-5x-4x-3x-2x-x.x等于多少?
(16x-13)/(4x-3)-(20x-24)/(4x-5)=(32x-30)/(8x-7)-(40x-43)/(8x-9)求x
8x^2(x+3)-8x(x+1)^2=8x^2-32
x+2/x+1-x+4/x+3=x+6/x+5-x+8/x+7 x=?
X(x平方-6x-9)-x(x平方-8x-15)+2x(3-x)其中x=-六分之一
3x+5x=8x.
4,8-x=3x(x
8x(x-5)=3x
(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
(8+x)*3=32+x
32+4/3x=8x
解方程(12x-10)/(4x-3)+(32x-34)/(8x-9)=(24x-23)/(8x-7)+(16x-19)/(4x-5)
12x-10/4x-3 + 32x-34/8x-9 = 24x-23/8x-7 + 16x-19/4x-5
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)....
(16x-13)/(4x-3)+(40x-43)/(8x-9)=(32x-30)/(8x-7)+(20x-24)/(4x-5)
