Question

How do you solve `-56=20-(-j)`?

Answer 1

`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`.
