Q. Google Classroom

\newline

If

2+2(8347-4783)=-2 j

, then what is the value of

-j

?

Given Equation: We are given the equation: $\newline$ $2 + 2(8347 - 4783) = -2j$ $\newline$ First, we need to simplify the expression inside the parentheses. $\newline$ Calculate $8347 - 4783$ . $\newline$ $8347 - 4783 = 3564$
Simplify Expression: Now, multiply the result by $2$ . $\newline$ $2 \times 3564 = 7128$
Calculate Result: Add $2$ to the product. $2 + 7128 = 7130$
Add to Product: We have simplified the left side of the equation, which now reads: $\newline$ $7130 = -2j$ $\newline$ To find the value of $-j$ , we need to divide both sides of the equation by $-2$ . $\newline$ Divide $7130$ by $-2$ . $\newline$ $\frac{7130}{-2} = -3565$
Divide by $-2$ : We have found the value of $-j$ . $-j = -3565$
