Subtract (j+2)-2(3-9j)

Answer 1

To simplify the expression (j+2)-2(3-9j), let's first distribute the 2 to both terms inside the parentheses:

(j+2)-2(3-9j) = (j+2)-6+18j

Next, let's combine like terms:

(j+2)-6+18j = j+2-6+18j

Now, we can combine the variables and constants separately:

j+2-6+18j = (j+18j) + (2-6)

Simplifying the expression:

(j+18j) + (2-6) = 19j - 4
