Step-by-step explanation:
Let's represent "a number" with x. We want to find the difference between x and 6, so we know that it is a subtraction problem. So far, we have the expression:
x - 6
We also know that this expression is less than 1. So, we are left with:
Now, let's solve for x.
x - 6 < 1 <--- Let's add 6 to both sides
