#j = -76#

Explanation:

#-56 = 20 - (-j)#
First, remove the double negative from the right side of the equation. Remember, a double negative makes a positive.
#-56 = 20 + j#
Now, solve for j by subtracting 20 from each side of the equation:
#-56 - 20 = 20 - 20 + j #
#-76 = j#
The solution is #j = -76#.
