Q. Evaluate the expression for

j = -8

.

\newline

2j =

_____

Identify expression: Identify the expression to evaluate. $\newline$ We are given the expression $2j$ and the value $j = -8$ . We need to substitute $-8$ for $j$ in the expression $2j$ .
Substitute value: Substitute $-8$ for $j$ in the expression. $\newline$ The expression becomes $2 \times (-8)$ .
Evaluate expression: Evaluate the expression $2 \times (–8)$ . $\newline$ Multiplying $2$ by $–8$ gives us $–16$ .
