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

Oct 4, 2016

$j = - 76$

#### Explanation:

$- 56 = 20 - \left(- j\right)$
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 $j = - 76$.
