Dear @Shin123 !

You just demonstrated and convinced EVERYBODY at this forum that you are not able to solve simple and simplest inequalities correctly.


In my view,  you produce more negative impact than positive.


Think about it !   We really do not need contribution like this !

-2n<10
==============
If you want to solve for n, you should say, "solve for n."
----
-2n<10
-n < 5
Add n
0 < n+5
Subtract 5
-5 < n
--> n > -5
-------------------
Notice multiplying by a negative changes the polarity.
