(3)/(x-1)+(4)/(x)is greater than or equal to(5)/(x-1)
Should the undefined values be included in answer?
---
They are not included in the solution.
---
3/(x-1) + 4/x >= 5/(x-1)
-----
Multiply thru by x(x-1) to get:
3x + 4(x-1) >= 5x
3x + 4x-4 >= 5x
7x -4 >= 5x
---
2x >= 4
x >= 2
=========================
Note:
The equations are undefined for x = 0
and for x = 1.
Those values of x = 0 and x = 1
are not greater than 2 so they do not affect
the solution set.
