4-n=-15 what does n equal

Step-by-step explanation:

Given

4 - n = - 15

n = 4 + 15

Therefore n = 19

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

the answer is 40.
