Step-by-step explanation:

Step 1: Define

2(n + 3) - 4 < 6

Step 2: Solve for n

1. [Addition Property of Equality] Add 4 on both sides:                                   2(n + 3) < 10
2. [Division Property of Equality] Divide 2 on both sides:                                n + 3 < 5
3. [Subtraction Property of Equality] Subtract 3 on both sides:                       n < 2

Here we see that any value n smaller than 2 would work as a solution to the inequality.
