Q. Evaluate the expression for

z = -1

.

\newline

2z - 14 =

_____

Substitute $z$ with $–1$ : Substitute $z$ with $–1$ in the expression $2z − 14$ . $\newline$ Calculation: $2 \times (–1) − 14$
Evaluate $2 \times (\text{–}1)$ : Evaluate $2 \times (\text{–}1)$ . $\newline$ Calculation: $2 \times (\text{–}1) = \text{–}2$
Subtract $14$ from extendash $2$ : Subtract $14$ from extendash $2$ to find the value of the expression. $\newline$ Calculation: extendash $2$ extendash $14$ = extendash $16$
