Respuesta :

n - 4 = 16   Given

  + 4  + 4   Cancel out 4 to isolate n variable

n = 20

Prove.

20 - 4 = 16

16 = 16

True.

In order to solve this equation you will have to add 4 on both sides and then you will have your answer.

[tex]n-4=16[/tex]

[tex]+4 +4[/tex]

[tex]16+4 = 20[/tex]

[tex]n = 20[/tex]

Which means your answer is "20."

Hope this helps.
