 P: 57 Hi I have a problem about Inequality. Let's suppose we have a inequality like this: $$axb≥d$$ and $$cxd≥d$$ 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?
 HW Helper P: 1,361 Is the second inequality meant to involve d on each side?
 P: 57 Mathematical Solution in Inequality İts a multiplication
 P: 57 I am sorry.Here the right one $$axb≥d$$ and $$cxf≥d$$
 Sci Advisor P: 6,039 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
