Hi I have a problem about Inequality.

Let's suppose we have a inequality like this:

[tex]axb≥d[/tex] and [tex]cxd≥d[/tex] so I want to find connection between a and d its possible to do something like that
Thanks

Just to be clear, is 'x' a variable or are you using it to indicate multiplication?

Is the second inequality meant to involve d on each side?

I am sorry.Here the right one

[tex]axb≥d[/tex]
and [tex]cxf≥d[/tex]

With no further information, there isn't much you can say about the relationship between a and d. Furthermore, the second inequality is of no help.

Questions: sign of a, sign of d, sign and size of b.

Because x is used so often in algebra, trig and higher mathematics disciplines, it's bad practice to use 'x' to indicate multiplication.

It's clearer to write your inequalities like this:

ab ≥ d
cf ≥ d

The times symbol is not ##x##, it is ##\times##. Use "\times" to get LaTeX to write it.
