Full solution

Q. Simplify the expression:

\newline

(q + 8) + -4 =

_____

Combine Like Terms: Combine like terms by adding the numbers together and keeping the variable $q$ as it is; $(q + 8) + (-4)$ becomes $q + (8 - 4)$ . $\newline$ Calculation: $q + 4$
Calculation: Check the result to ensure no mathematical errors were made. $\newline$ Calculation check: $q + 4$ remains unchanged as there are no further simplifications.
