For this case we have a first degree equation, whose variable is represented by "n". We must find the value of n. Let:
[tex]4n + 11 = 39[/tex]
We subtract 11 from both sides of the equation:
[tex]4n + 11-11 = 39-11\\4n = 28[/tex]
We divide between 4 on both sides of the equation:
[tex]\frac {4n} {4} = \frac {28} {4}\\n = 7[/tex]
Thus, the value of n is 7.
Answer:
[tex]n = 7[/tex]
