Question

Combine like terms to create an equivalent expression. -(4)/(7)p+(-(2)/(7)p)+(1)/(7)

Answer 1

Explanation:

You can only combine terms that are the same, which means you can only combine the fractions with p attached. A + and - make a -. The second fraction changes to negative or subtraction which ever way you want to say it. -4 - 2 = -6 and the bottom number always stays the same and you keep the letter attached. You can not combine 1/7 because it does not have a p attached. You would leave it the same.
`(-6)/(7)p +(1)/(7)`

Answer 2

-6/7p + 1/7

Explanation:

Like Terms: terms that have the same variables and powers

In this equation the like terms are -4/7p and -2/7p

First solve that, which will be -6/7p + 1/7

You have to leave the 1/7 alone because there aren't any more numbers with no variables.
