Q. Evaluate the expression for

w = -1

\newline

-13w - 7 =

_____

Write expression substitution: Write the expression $−13w − 7$ after substituting $w = −1$ .
Substitute $−1$ for $w$ in $−13w − 7$ .
$−13(−1) − 7$
Substitute $w$ in expression: Evaluate $–13(–1) − 7$ . $\newline$ $–13(–1)$ is the same as $13$ because the product of two negative numbers is positive. $\newline$ $13 − 7$
Evaluate expression: Subtract $7$ from $13$ . $\newline$ $13 - 7$ equals $6$ .
