Ok but I am trying to understand this problem and how to solve it... I am in Pre algebra and I can get some of it but some of it is so confusing to me

Answer 3

think of "w" as cookies or some other object

Answer 4

So I just subtract it then then divide it into the answer?

Answer 5

Exactly !

Answer 6

you can subtract like terms

Answer 7

2w - 7w = -5w

but you cannot subtract if they are not both same

Answer 8

for example you cannot combine below :

2w - 7z

Answer 9

oh ok
so then there is no equation for 2w-7z?

Answer 10

because they are not like terms correct?

Answer 11

You're right

2w - 7z = 10


we cannot do anything here because they are not like terms
