Hi there.
Thanks for using Brainly.
First let us remove parentheses.
Therefore our problem:
4n + 8 + n - 1 = 2n + 14 + 5
After, we can then distrubute 4 through parentheses.
4n + 8 + n - 1 = 2(n+7)+5
Then, we can distribute 2 through the parentheses.
Therefore: 4n + 8 + n -1 = 2n + 14 + 5
After, to make this problem easier we can collect like terms.
5n + 8 - 1 = 2n + 14 + 5
Since they're collected we can subtract the numbers.
5n + 7 = 2n + 14 + 5
Then, we can add the remaining numbers.
5n + 7 = 2n + 19
We're in a situation where we have two varibles on different sides of the equation.
To fix this we can move 2n to the other side by changing it's sign.
5n - 2n + 7 = 19
Subtract 7 from both sides. (We need to get n by itself)
5n - 2n + 7 = 12
Then - we can subtract 5n - 2n to get 3n.
3n = 12
Divide 3 from both sides.
3/3 12/3
Therefore our answer is 4.
ANSWER:
N = 4
