Question

Combine any like terms in the expression. If there are no like terms, rewrite the expression.

5u+5u+u

If there a letter in front of the number and the letters are the same, add the numbers up. If there's only a letter without a number, it's one.

So everything is (11u)

So they can all be combined to equal 11u
