5p-14=8p+4=. show work please
Ainat [17]
No Problem!
5p-14=8p+4
I assume this is the whole problem set up properly, so now, lets subtract the left side by 5p, and then the right side.
-14=3p+4
As you can see, the 5p cancels out on the left side, and the p leftover is what 8p-5p equals.

Now, subtract both sides by 4.
-18=3p
Now, simply divide both sides by 3 to equal
p= -6
The reason we do the divide and multiplying last is because doing it first would only make it much harder.
This is the simplest way I know of to do it. If you don't understand, just ask me.
Hope it helped!
