Combine like terms
@breanna1999 i don't get in.
You have terms in algebra. For example in this equation you have p and your number. You have to combine them(or add) together.
so add the numbers together that haves the same letter with it?

Yes correct but pay attention to the negative numbers and make sure you add correctly
@breanna1999 okay, so how do you work with the negative number?
You have a positive 4p plus a negative 7p. You can rewrite this as 4p-7p. If you put this into a calculator you would get -3p or you could draw a number line and place a point on 4 and go backwards 7 spaces
@breanna1999 ohh okay i think i got it :). thank you!!!
