Full solution

Q. Evaluate the expression for

q = -7

.

\newline

-1 - q =

_____

Identify and Substitute: Identify the expression and substitute the given value for $q$ . $\newline$ Substitute $–7$ for $q$ in the expression $–1 − q$ . $\newline$ Expression: $–1 − (–7)$
Evaluate Expression: Evaluate the expression $–1 − (–7)$ . $\newline$ The subtraction of a negative number is the same as addition. $\newline$ So, $–1 − (–7)$ is equivalent to $–1 + 7$ . $\newline$ Calculate: $–1 + 7 = 6$
