Answer 4

welcome :)

Answer 5

Like terms are terms with the same variables.
Terms with u are like terms. They can be added or subtracted together.
Terms with v are like terms. They can be added or subtracted together.
A term with v and a term with u are not like terms because of the different variables and cannot be added or subtracted together.

\(3u + 7v + 4u – 2v =\)

\(3u + 4u + 7v - 2v \)

\(7u + 5v\)

Also notice that the sign of a term, + or -, is the sign before it. Notice the last term of the original expression is -2v.
