Question

Describe how to combine like terms in the expression 3n + 4n − 2.

Answer 1

3n + 4n − 2.

Like terms add 3n + 4n

7n-2

Answer 2

add the 3n and 4n together to get 7n bc they have the same variable, then minus 2 but it would not have a definite answer bc 2 DOES NOT have n as a variable
so the answer is...
7n-2
