Help me please. what is the solution for<br> 4≤n−4

notka56 [123]

Answer:

n $\geq$ 8

Step-by-step explanation:

You add 4 to both sides to make n the only thing on one side. Then to make the answer look better you move n to the left side and flip the symbol because n changed sides.

$4\leq n-4\\ 4+4\leq n-4+4\\ 8\leq n\\ n\geq 8$
