Answer:
6 ≤ n+15 ; -9 ≤ n
Step-by-step explanation:
In order to write this equation we start with 6 then we add the less than or equal to symbol. To to find the other side of the inequality you need the sum(which means to add) of n and 15, so you get 6 ≤ n+15.
To solve this you just need to follow one step. You must subtract 15 from both sides to get the variable by itself. This leaves us with -9 ≤ n.
