Question

What is 4n + 11 = 39

Answer 1

n=7

39-11 =28 so think what times 4 equals 39?

Well if you know your multiplication tables you would 7•4=28 and add that to 11 you get 39.

Answer 2

For this case we have a first degree equation, whose variable is represented by "n". We must find the value of n. Let:

`4n + 11 = 39`

We subtract 11 from both sides of the equation:

`4n + 11-11 = 39-11\\4n = 28`

We divide between 4 on both sides of the equation:

`\frac {4n} {4} = \frac {28} {4}\\n = 7`

Thus, the value of n is 7.

Answer:

`n = 7`
