While reading a paper i have come across an equation in the following form;

a = b - f(c) $\leq$ 1

What is this style of equation called and how do you solve them?

Thanks

It's not an equation, it's an inequality (or, half of it is). It means exactly what it says: a is equal to b - f(c), and both are less than or equal to 1. You can't do anything more with it until you know the values of the constants.

Thanks Number Nine. I am not familiar with this

The values are;

a = 1 - 0.8√13 $\leq$ 1

Thx

The author has determined (by some preceding working) that a = 1 - 0.8√13, and is now pointing out that this value is ≤ 1. Presumably the author needed to show that a ≤ 1, and has now done so.
