Question

Solve the equation
3(n+4)=21
So what represents n?

Answer 1

n=3

Explanation:

3(n+4)=21

First Step: Divide 3 on both sides

n+4=7

Second Step: Subtract 4 from both sides

n=3

Answer 2

`n = 3`

Explanation:

`3(n + 4) = 21 \\ 3n + 12 = 21 \\ 3n = 21 - 12 \\ 3n = 9 \\ (3n)/(3) = (9)/(3) \\ n = 3`
