Six is at least four more than a number?

Hi! How are you.

This is an expression of a inecuation, so we have to express all the terms in a mathematic form :

We express, six is at least four more than a number (that we will call x) :

6≥4 + x

Pass the number 4 to the left side : 6 - 4 ≥ x

So we have : 2≥ x, so finally we can afirm that two isgreater than or equalto x.
