Question

What are like terms?

Answer 1

like terms are term that has the same variable
Ex: 5a and 19a are like terms because they have they same "a" varaible
You can simplify like terms only by add or subtract the numbers like terms
Ex:
`2d + 3g + 4g - 5s+9d`
in this case,
`3g` and
`4g` are like term so we add them together, 4+5= 9, so
`9g`, is simplified answer.
Then
`2d` and
`9d` are like terms again so we also add them together, 2+9 =
`11d`

`-5s` is alone so you just keep it the same, remember your negative sign.
The answer will be:
`9g + 11d - 5s`
