16 − -4n = 92<br> Can someone please solve this?
Sladkaya [172]

Answer:

n=19

Step-by-step explanation:

Question: 16--4n=92

1) Change the two negative signs to a (+):

16+4n=92

2) Subtract 16 from both sides:

4n=76

3) Divide both sides by 4:

n=19

Footnotes:

- When you have two (-) signs next to each other, they cancel and are replaced by a (+)
