# Calculate minimum value based on constraints

This seems like a bit of a simple question in amongst all the 'proper' maths, but I'm a bit rusty...

If I have the following constraints:

$$A = c(T - x)$$

$$x - A > 0$$

$$0 < c < 1$$

I don't think that there is a way to calculate the minimum value that x can be to satisfy these contraints (for a fixed c and T) without using an iterative approach. Is that correct?

What about $A$, is it fixed? –  Michael Albanese Oct 11 '12 at 11:52
