Which is a solution of the inequality?
p + 4 – 2(p – 10) > 0

Hi Laila

p+4 -2(p-10)>0

The first thing you need to do is simplify the both sides

So that will be

p-2p + 4+ 20 > 0

-p + 24 > 0

-p > 0-24

-p > -24

Now since we can not have the negative sign in front of P, we need to do something. What we need to do is divide both sides by -1

-p/-1 > -24/-1

p < 24

Remember to change the symbol.

I hope that's help and if you have any further questions please let me know :)
