Answer:
n=19
Step-by-step explanation:
To solve, we need to get n by itself.
First, move all the numbers to one side of the equation
4-n=-15
Subtract 4 from both sides
4-4-n= -15-4
-n=-19
Now all the numbers are on one side, and the variables are on the other. n is still not by itself, or is being multiplied by -1. To undo this, divide both sides by -1.
-n/-1=-19/-1
n=19
