Full solution

Q. Simplify the expression:

\newline

8 + (q + -1) =

_____

Combine numbers in parentheses: Combine the numbers inside the parentheses. $q + (–1)$ becomes $q - 1$ .
Add $8$ to simplified expression: Now add $8$ to the simplified expression inside the parentheses. $8 + (q - 1)$ becomes $8 + q - 1$ .
Combine like terms: Finally, combine the like terms. $8 - 1$ is $7$ , so the expression becomes $q + 7$ .
