Combine the like terms to get #15u#

Explanation:

Faribault Middle School

Like terms are terms that have the same variable raised to the same power.

#8u#, #7u#, #3u#, and #-3u# are all like terms, as their shared variable is #u# raised to the first power.

We'd then add and subtract as if they were normal numbers.

#8+7+3-3=15#, but don't forget about the variable #u#, to get #15u#
